build your Simulation Optimization application in weeks

Manage any business constraints and objectives

Surrogate modeling

Reduce your simulation time by orders of magnitude thanks to innovative Surrogate Modeling techniques. 

Manage discrete variables

Solve a wide range of problems mixing quantitative and discrete decision variables (float, bool, int, set, list).    

Analytical constraints

Add constraints analytically to your optimization model by using built-in nonlinear mathematical operators. 

Black-box constraints

Use the output values of your simulation anywhere in your optimization model: constraints and objectives. 

Leverage past simulations

Save still more simulation time by using previous simulation results to warm-start Hexaly Optimizer.

Adapt to any runtime

A call to the simulation may require seconds, minutes, or hours of running time: Hexaly Optimizer adapts.  

Adapt to any landscape

The solution space can be nonlinear, nonconvex, nonsmooth, and highly noisy: Hexaly Optimizer adapts. 

Black-box optimization

Adapt to any black-box optimization problem: from design optimization to hyperparameter tuning.

Hexaly Optimizer has been tested and confirmed by our team as the best GLOBAL solver available on the market. With this optimizer and innovative approaches, the Maxflow app has a superior optimization capability for its automated workflows.

Chau Le President, Maxflow Technology

Developing and deploying a tool like Smart Agri took less than three years. This digital simulation and optimization tool for integrated and organic fertilization was initiated in mid-2015 and has today reached the initial business solution rollout phase. We can support knowledge projects with extremely long-term goals and effectively develop new tools on behalf of our clients and operational performance.
