Evaluating bound‐constrained minimization software

Bound‐constrained minimization is a subject of active research. To assess the performance of existent solvers, numerical evaluations and comparisons are carried on. Arbitrary decisions that may have a crucial effect on the conclusions of numerical experiments are highlighted in the present work. As a result, a detailed evaluation based on performance profiles is applied to the comparison of bound‐constrained minimization solvers. Extensive numerical results are presented and analyzed.
