  Despite the success of the Colonial Competition Algorithm (ICA) in solving optimization problems, this algorithm still suffers from repeated entrapment in the local minimum and low convergence speed. In this paper, a new version of this algorithm, called Modified Orthogonal Chaotic Colonial Competition (COICA), is proposed. In the policy of absorbing the proposed version, each colony seeks the space to move towards the colonizer through the definition of a new orthogonal vector. Also, the possibility of selecting powerful empires is defined through the boltzmann distribution function, and the selection operation is performed through the roulette wheel method. The proposed multilevel perceptron neural network (MLP) algorithm is used to classify standard datasets, including ionosphere and sonar. To evaluate the performance of this algorithm and to evaluate the generalizability of the trained neural network with the proposed version, the K-Fold cross-validation method has been used. The results obtained from the simulations confirm the reduction of network training error as well as the improved generalizability of the proposed algorithm. Manuscript profile

  One of the most influential components in the sales process is the design and design of the packaging structure. This design is sometimes inspired by product-related elements such as product geometry, product origin, or product geography. As customers nowadays have more power than ever, they tend to look at the descriptions and ingredients of each These products are not comparable to them. Of course, given the fact that there is still a bulk buying culture in our country, there is still a long way to see the growth of packaging products, but these days, exporters have realized that No matter, this sector will not succeed in the global market, and we all know It was because of this package that we handed over the zooghfran to Spain, and if the manufacturer of the corners of the box shows that it is in order to improve the packaging of its products from bad to medium and still a place for innovative packaging in the country's industry It is not intended to be included in this paper. In this paper, we have reviewed the packaging packing protocols, so that we can take steps to help producers and increase sales. Manuscript profile

  The increasingly rate of change and as a result shortening product life cycle, has emphasis on innovation among industrial companies. The purpose of this research is to briefly discuss the role that innovation plays in global competition and to investigate the relationship among influential variables on innovation in petrochemical companies. Drawing from literature review we developed a research model. It consists of 26 factors and then with utilizing DEMATEL Fuzzy technique, they were reduced to seven variables, namely, culture of change, management performance, focusing on clients’ demand, financial conditions, product flexibility, using new technology and government support. Then the effects of above factors on organizational innovation have been assessed. Results emphasizes on vital role of culture of change among employees that must be at center of interest on managers. Also results indicate that clients’ interest is an independent variable that neither effects nor effected by other variables. Among other findings, results indicate that culture of change, management performance and using modern technologies are the most vital factors affecting innovation in petrochemical companies. Investment variable has been identified as an independent variable that has great effect on a number of effective variables in petrochemical companies. Manuscript profile

  In the path of economical development for promoting technology levels of a country, different methods of acquisition of technology, improving current technology and also developing and boosting a new technology by localizing and also R&D are used. Although transferring and technology acquisition is considered as an effective tool in developing industries but importing machineries and industrial tools does not just mean acquisition. The appropriate acquisition is accompanied with technical knowledge and the knowledge of how to use it. In this regard, the balance between technology strategy and business strategy is extremely important on the increase of competitive advantage and also to technology adaption in the national level. The aim of this research is to identify correlation of Porter's five strategic factors with technology acquisition modes with respect to cho and you's technology absorption model and also determine the correlation of these factors with the absorption of technology method and finally provide a model to align strategic and technological goals of company. Nonparametric test is used for achieving research purposes. Chi-square test is used to determine the independence or correlation between independent variables and the dependent variable, and Kendall tau b is used to determine the homogeneity of the criteria. Based on the results, the alternative of buyers bargaining power has the highest correlation with technology acquisition methods. Manuscript profile

  Increasing the dimension of the databases have involved the attribute reduction as a critical issue in data mining that it searches to find a subset of attributes with the most effectiveness on the hidden patterns. In the current years, the rough set theory has been considered by researchers as one of the most effective and efficient tools to the reduction. In this paper, the soccer league competition algorithm is modified and adopted to solve the attribute reduction problem for the first time. The ability to escape the local optimal, the ability to use the information distributed by players in the search space, the rapid convergence to the optimal solutions, and the low algorithm’s parameters were the motivation of considering the algorithm in the current research. The proposed ideas to modify the algorithm consist of utilizing the total power of fixed and saved players in calculating the power of each team, considering the combination of continuous and discrete structures for each player, proposing a novel discretization method, providing a hydraulic analysis appropriate to the research problem for evaluating each player, designing correction in Imitation and Provocation operators based on the challenges in their original version. The proposed ideas are performed on small, medium and large data sets from UCI and the experimental results are compared with the state-of-the-art algorithms. This comparison shows that the competitive advantages of the proposed algorithm over the investigated algorithms. Manuscript profile

  Permeability is one of the most important petrophysical parameters that play a key role in the discussion of production and development of hydrocarbon fields. In this study, first, the magnetic resonance log in Asmari reservoir was evaluated and permeability was calculated using two conventional methods, free fluid model (Coates) and Schlumberger model or mean T2 (SDR). Then, by constructing a simple model of artificial neural network and also combining it with Imperialist competition optimization (ANN-ICA) and particle swarm (ANN-PSO) algorithms, the permeability was estimated. Finally, the results were compared by comparing the estimated COATES permeability and SDR permeability with the actual value, and the estimation accuracy was compared in terms of total squared error and correlation coefficient. The results of this study showed an increase in the accuracy of permeability estimation using a combination of optimization algorithms with artificial neural network. The results of this method can be used as a powerful method to obtain other petrophysical parameters. Manuscript profile

  prudence and the paris convention Competition has different titles, but fair competition in recruitment make the benefits of a all society. But in some instance, competitor use irrecoverable harm to their compet-ing commercial interests by using illegal and unprotected methods. In this case, it is a type of competition in which business competitors use equipment unfairly and compete for unfair titles. Unfortunately, there is no exact definition of the meaning of unfair competition, but in addition to unfair competition, which is discussed in private law, there is no definite way of defining public rights and economic rights, which they call competition law. In the law of instance such as offensive and discriminatory pricing, monopoly, similarity of name and trademark, as well as cases in the field of industrial property rights, we can mention the obstacles to fair competition, in other words, unfair competition. In Imamieh jurisprudence, with its rich resources, it is prohibited to disor-derly competition, among which, in addition to many verses and narratives, it is possible to mention cases such as hoarding, reckoning, and the rule of lawlessness. Given the above, it is clear that the law defends a fair competition and request to reform the com-petitive relationship between individuals, which, assuming this important, can be seen as a Justice-centered economy. In this study, to clarify the nature of Fair competition , con-cept and examples of unfair competition, and to better understand the unfair competition law, compare it with some of the relevant institutions in the Paris Convention and other conventions.

  The power vacuum within the Central Asia in the aftermath of the Cold War led the regional actors to create an integrative structure. Establishment of the Shanghai Cooperation Organization (SCO) signifies the sensitivity and determination of its founding members towards international, regional and local issues. The inherent rivalry and conflict in facing security crisis within the cooperative framework of SCO was the natural result of the presence of two nuclear and economic power, Russia and China, alongside micro-actors. This paper explains the nature of the communication system governing the relations among SCO members through the regional security arrangements approach. The hypothesis that “gathering of various approaches within the SCO would lead to increased cooperative relations, but also competetive and interest-maximiser” will be tested against various historical, geopolitical and economic variables.

  This study aimed to investigate the factor structure and psychometric properties of the Persian version of the lay beliefs about competition scale (Kesebir et al., 2019) in a group of Iranian high school students. For this purpose, 464 students of Evaz city, located in the south of Fars province, who were studying in the academic year of 2022-2023; they were selected Convenience sampling method. They responded to the lay beliefs about competition scale (Kesebir et al., 2019) and achievement goals questionnaire (Elliott et al., 2011). The content, construct, convergent and divergent validity of the mentioned scale were investigated using the opinion of educational psychology experts, exploratory factor analysis, confirmatory factor analysis, correlation coefficients of component scores with related variables and correlation between scale components. Cronbach's alpha coefficient was used to investigate the reliability of the scale. Experts confirmed the representativeness of the scale items to measure the positive and negative lay beliefs about competition in the two-factor model presented by Kesebir et al. (2019). Exploratory factor analysis showed that there is a two-factor structure of lay beliefs about competition including positive and negative beliefs about competition among Iranian students. The lay beliefs about competition model test includes positive beliefs and negative beliefs confirming the two-factor structure of this scale in line with the main research. Also, the logical connection of the components of positive and negative lay beliefs about competition with the components of achievement goals indicates the convergent validity of this scale. The average correlation of two positive and negative components of the lay beliefs about competition confirms the divergent validity of this scale. In addition, Cronbach's alpha coefficients confirm the reliability of the scale. In total, the findings of the research show that the Persian version of the mentioned scale has suitable psychometric indicators for measuring positive and negative lay beliefs about competition in the group of Iranian high school students; and it has the necessary efficiency to measure the mentioned beliefs.
