Software tool for stochastic simulation as well as for the stochastic optimization

[John Oksz]

Hello Python World,

I am starting work on stochastic approach.

I plan to work in decision support field in environmental engineering
so I will use both the stochastic simulation as well as the stochastic
optimization.
I would like to select the best for both approaches software tool.

what you suggest ... Matlab ... python ... something else?

Any thoughts would be appreciated,
John
