Raw data of the EXPensive Optimization benchmark library (EXPObench)

These are the raw data of the results of several surrogate-based optimization algorithms, applied to four different real-life expensive optimization problems. Included are the computation time used by the algorithm, time spent on evaluating the expensive objective function, and the values of the decision variables and the objective at every iteration and at the optimum.A file to plot the results is also included, and the plots itself as well.
