The objective is to improve the optimizers, to optimize the optimization algorithms. Specific metrics would be to maximize the probability of finding the global optimum and robustness to aberrations (constraints, nonlinearities, stochastic response, discontinuities, flat spots, etc.) while minimizing computational work (of both the algorithm and number of function evaluations) and minimizing complexity (for either programmer or user). In any one optimizer, there seem to be dozens of enhancements the lead to improvements.
