The following comma-separated files contain detailed results from the application
of mixed-integer derivative-free solvers to the problems solved in the paper:
``Review and comparison of algorithms and software for mixed-integer derivative-free optimization'' by Nikolaos Ploskas and Nikolaos V. Sahinidis.
Five instances were solved from randomly generated starting points (DAKOTA/SOGA, does not use the provided starting points but uses randomly chosen starting points, thus it was also ran five times. TOMLAB/GLCDIRECT, TOMLAB/GLCFAST, and TOMLAB/GLCSOLVER were ran once since they discard the starting point).
The following format is used for the results files:
Column 1 'problem' contains the name of the test problem solved
Column 2 'solver' contains the name of the solver used
Column 3 'time' contains the cpu time taken by the solver
Column 4 'solution' contains the best solution found by the solver
Column 5 'calls' contains the number of function calls used by the solver
Column 6 'best call' contains the iteration counter when the best solution was found by the solver
