The development of theory and applications of multi-agent systems determined in the last years a real revolution regarding the modeling of complex systems. The structure of any agent-based computational model contains the next elements: parameters, variables, algorithms and agents. We make a comparative analysis of three multi-agent computational algorithms (RAND, NMEM and WMEM) used to harvest grain in a bi-dimensional lattice. The first algorithm

Under the present circumstances, the international trade is characterized by a series of highly important processes, such as: a) The growth of the national potential of economic competitiveness is ever fluctuating, being influenced almost decisively by the evolution of the technical progress and by its implementation in the economic and social life; b) The polarization of the trade exchanges; c) The internationalization of the financial markets;

Traditional export-import operations include the following steps: (1) the conclusion of the international trade contract between the exporter and importer; (2) sending the goods to the importer by the exporter; (3) payment by the importer to export goods. Alongside these traditional operations, foreign trade operations are conducted through stock of goods and values, export and import tenders, the modern counterpart, licensing of patents, consulting

The period of transition from socialist economy to capitalist one had a strong impact over the Romanian foreign trade. The external disequilibrium is revealed by the current account deficit and high rate of depreciation of national currency. In the last years, the depreciation of national currency was stopped but the problem of current account is still unsolved. In order to solve this problem, Romania must use the financial resources obtained from
