perfect blend of programming and modeling features

Why Hexaly Modeler?

All existing modeling languages have the same flaw: they become useless when manipulating or editing data or results. They force you to use external scripts or languages.

On the contrary, Hexaly Modeler is a dynamically typed, imperative language with unique structured programming features that ensure easy modeling for any type of optimization problem.

    x[0..7] <- bool();
    weights <- { 10, 60, 30, 40, 30, 20, 20, 2 };
    prices <- { 1, 10, 15, 40, 60, 90, 100, 15 };
    constraint sum[i in 0..7](x[i]*weights[i]) <= 102;

Model:  expressions = 62, decisions = 8, constraints = 1, objectives = 1
Param:  time limit = 10 sec, no iteration limit

[objective direction ]:     maximize

[  0 sec,       0 itr]:            0
[ optimality gap     ]:      100.00%
[  0 sec,   16402 itr]:          280
[ optimality gap     ]:           0%

16402 iterations performed in 0 seconds

Optimal solution:
  obj    =          280
  gap    =           0%
  bounds =          280

Concise & mathematical

With Hexaly Modeler, using paper or LaTeX formulas to model your problems is over. Coupled with the richness and expressiveness of Hexaly, our modeling language is understandable even to people who do not know the Hexaly Modeler syntax.

Efficient

Hexaly Modeler takes full advantage of its powerful integration with Hexaly Optimizer. Writing your models in Hexaly Modeler gives you the best possible modeling times and performance compared to other dynamic languages like Python.

Builtin I/O features

You do not have to worry about decoding your data anymore. Hexaly Modeler does it for you in a few lines. It has all the features you need to easily read various file formats (like JSON or CSV) or manipulate dates and times. It also has built-in support for many charsets and encodings.

Easy integration

Hexaly Modeler works as a standalone program, but it also has an API you can call from your favorite languages like Python, C#, C++, or Java. You can run your Hexaly Modeler programs from your applications and easily exchange data. If you miss a feature, code it in your language and expose it directly in Hexaly Modeler.
