E2: A basic optimization method

Matlab Code implementation of E2 optimization algorithm

The presented algorithm emphasizes that by simply implementing the primary principles of optimization (exploration and exploitation), a difficult problem can be effectively solved, potentially eliminating the need to develop or apply a complicated search method.

For this aim, we propose a basic and simple optimization method based on the exploration–exploitation concept, named E2. Based on the simulation results, it is found that on average, the sinusoidal function is a promising method for exploitation. Over a set of engineering design problems, it is observed that the results found by E2 are comparable to those of other methods.

This code presents the sinusoidal version of E2.
