In this paper, a fuzzy controller is presented in order to achieve the maximum power in a solar cell. For improvement of the controller performance and achievement of the maximum power, the fuzzy controller variables are improved by the Grasshopper Optimization Algorithm (GOA). This algorithm has flexibility and fast convergence. In this paper, the ISE evaluation index is employed as the cost function of algorithm to verify the obtained results. The results show that under the supposed conditions, the power value of the solar cell utilizing the suggested algorithm has increased compared to other algorithms. In the simulation, the power value using the proposed algorithm is 182.3 watts and the cell efficiency in this case is 99.97%. Therefore, the achieved results show at least 0.03% and 1.2% improvement, respectively in power and efficiency, compared to some examined methods.

The present study investigates the effectiveness of several new meta-heuristic (MH) methods in solving virtual machine (VM) to physical machine (PM) placement (VMP) in cloud data centers. More specifically, Coati optimization algorithm (COA) is properly adapted for solving VMP by introducing several operators for the phases of the algorithm. Several emerging and classic meta-heuristics are also included in the evaluations, including genetic algorithm, chemical reaction optimization, Harris hawk optimization (HHO), and electron valley optimizer (EVO). Two main parameters are included in our evaluations, including power consumption and resource wastage. The algorithms are evaluated in terms of their ability to reduce power consumption and resource wastage in VMP, and also in terms of their execution times. A set of evaluations with synthetic VMs are performed. The results indicate that all MHs perform almost similarly, while emerging methods (COA, HHO, EVO) have a marginal benefit.
