 Currently, it's possible to optimize user-defined functions with a few Stochastic Local Search basic methods, that are composed by building blocks also provided in the package. Evaluations of functions are made in parallel, using `remotecall_fetch`, the `@sync` and `@async` macros and `Tasks`. It's possible to instantiate multiple instances of a search technique, or different techniques, that run on the same problem.
