Hexaly Modeler

Usable by both developers and mathematicians, Hexaly Modeler fills the gap between modeling and programming languages. Hexaly Modeling Language is natively integrated with Hexaly Optimizer, at no extra cost.

perfect blend of programming and modeling features

Why code with Hexaly Modeling Language?

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

On the contrary, Hexaly Modeling Language is a dynamically typed, imperative language with unique structured programming features that facilitate modeling for all kinds of optimization problems: linear and highly non-linear problems, combinatorial problems, set based problems…

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 & close to mathematical formalism

With Hexaly Modeling Language, the use of 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 Modeling Language syntax.

Efficient

Hexaly Modeling Language takes full advantage of its powerful integration with Hexaly Optimizer. By writing your models in Hexaly Modeling Language, you get 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 Modeling Language 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 Modeling Language works as a standalone program, but it also has its API that you can call from your favorite languages like Python, C#, C++, or Java. You can run your Hexaly Modeling Language programs from your applications and easily exchange data. If you miss a feature, code it in your language and expose it directly in Hexaly Modeling Language.
