The Hybrid Projected Gradient-Evolutionary Search Algorithm HPGES algorithm uses a specially designed evolutionary-based global search strategy to efficiently create candidate solutions in the solution space. A local projection-based gradient search algorithm is then used to improve the candidate solutions at each generation and to construct new potentially improved candidate solutions for the next generation of the evolutionary search. The search terminates when a certain convergence criterion is met. The details of different components of the hybrid algorithm are described in detail in the following sections.
