As reported in #936 , the regression tests for the random search layout optimizer can sometimes fail. I believe that the cause for this is that the optimizer is run for one second during the test; however, depending on the machine, it may take more or less steps over that period.
This PR alters the
LayoutOptimizationRandomSearch
code to make it modular, and then adds a debugging version of the optimization routine that will take a fixed number of steps (in particular, 100 random perturbations per generation, 1 individual per generation, and 2 generations).This should enable reproducible regression test results.
