Users can define any uncertain parameters with mark ups. Special features are available in Optimize (also called AHM) to define relative permeability parameters and regional multipliers automatically.

History match error functions can be created automatically, while advanced syntax options allow defining more specific functions.

Optimize (also called AHM) and RE-X, the RE-Studio Experimental Designs solution, have many similarities, such as the designs of the parameter values panels and the objective function managers. It is possible to open in Optimize (also called AHM) a project created in RE-X. This allows a smooth transfer of the design data.

Optimize (also called AHM) has a choice of three optimization algorithms : CMA-ES, Separable CMA-ES, and Nelder-Mead. Proxy Assistance is available to accelerate convergence. The proxies can be initialised with exploration runs.
