Finding the optimal global solution in optimization problems is such an important issue that various related approaches have been proposed so far. An effective attempt before solving such problems is to reduce the search space in such a way that the search is concentrated in a smaller subspace and therefore the probability of finding the optimal global solution increases. In this article, three methods of clustering, classification and association in data mining are used to reduce the search space in a nonlinear optimization problem. After that, using the Genetic Algorithm, the problem is solved on the entire initial feasible space and the reduced spaces resulting from three data mining methods. The results show that by combining data mining methods and Genetic Algorithm, more accurate approximations for the global optimal solution of the problem can be obtained.

In this paper, the parabolic inverse problem with the unknown source parameter is introduced and we solve the problem using the operator splitting method. To solve this problem, it is necessary to determine the source parameter using an overspecify condition, and then by separating the problem and converting it into simpler sub-problems, each sub-problem is solved using Fourier transforms. Also, while providing numerical examples of efficiency and convergence, the proposed method for solving the parabolic inverse problem is shown.

Project control is one of the most important research topics in science and engineering that is closely related to management. In this paper, we introduce project control and project management and explain their differences. We try to describe project control in networks. In this case, we give a brief overview of precedence networks, probabilistic networks, and graphical evaluation and review networks. For planning with limited resources, we will study PERT and GERT networks. Finally, we will introduce the two softwares that are used to solve project control problems and examine their differences.
