x, f input size to bayes_optimization_disc

[edz504]

Hey Ruben,

Thanks for this great package. I'm looking to understand why in your bo_disc.cpp example, the input x and fmin that are modified to contain the optimizer and the optimal value are initialized with size 128. I notice this value appear in many other places, so I was hoping you could help me see why.

Thanks!

Standard size value.
