A new package that performs global optimization is presented. The package uses adaptive grid refinement. Inequality constraints, which may even be nonlinear and may represent multiple separate regions of the search space, are allowed. The package can find multiple true minings if they exist and can also define optimal regions as specified by the user.

$\begingroup$ @Mr.Wizard I'd like to, but I've been quite busy recently, and also now. Basically, upon a superficial look at the code, it is a matter of variable localization (using Module or Block inside Compile).If this is not done, those variables are considered global by Mathematica.
