Modeling

The Model

The object Model is the key component. It should be imported :

• Java
• Python

import org.chocosolver.solver.Model;

from pychoco import Model

Then, an instance of a model is built as follows:

• Java
• Python

Model model = new Model();

model = Model()

A name can be attached to an instance:

• Java
• Python

Model model = new Model("my problem");

model = Model("my problem");

Model is the top-level object that stores declared variables, posted constraints and gives access to the Solver.

Once the model is created, variables and constraints can be defined.
