Parallel constraints evaluation?

[osamimi]

Is there a way to have constraints evaluated in a parallel/vectorized fashion like it can be done for the cost function by setting parallel_objective arg of fmin() to a callable?
There are plenty of problems where all or most of the computation is spent on finding a feasible solution.

Sorry, this is currently not possible out of the box. However, addressing issue #258 would allow this by design.

Otherwise, one could write a wrapper or inherited class for ConstrainedFitnessAL using or modifiying its __call__ method.
