tomato-cooker 0.2.1

Minizinc problem solver

cooked-tomato

Timetable scheduler for phone attention turns in Som Energia

History

This project is the result of an internal Som Energia Hackathon held on 11-03-2022 about MiniZinc with the goal of reimplementing the previous solution based on a pruned backtracking.

Prerequisites

Before you begin, ensure you have met the following requirements:

• You must have at least python 3.8. You can get this python version through pyenv. See more here -> https://github.com/pyenv/pyenv#installation
• You should have a Linux/Mac machine. Windows is not supported and we are not thinking in it.

Installation

pip install cooked-tomato

Usage

import asyncio
from tomato_cooker.grill import GrillTomatoCooker
from tomato_cooker.models import TomaticProblem, tomatic

# define a problem
tomatic_problem_params = {
    "nPersons": 4,
    "nLines": 2,
    "nHours": 3,
    "nNingus": 1,
    "nDays": 5,
    "maxTorns": 2,
    "nTorns": [3, 3, 3, 3,],
    "indisponibilitats": [
        {1}, {1}, {2}, {1}, {1},
        {2}, {2}, {2}, {2}, {2},
        {3}, {3}, {2}, {3}, {3},
        {2}, {3}, {2}, {2}, {1},
    ]
}
tomatic_problem = TomaticProblem(**tomatic_problem_params)

# choose a list of minizinc solvers to user
solvers = ["chuffed", "coin-bc"]

# create an instance of the cooker
tomato_cooker = GrillTomatoCooker(tomatic.MODEL_DEFINITION_PATH, solvers)

# Now, we can solve the problem
solution = asyncio.run(tomato_cooker.cook(tomatic_problem))
print(solution)
