THE PRODUCT, IN PRACTICE

## Run MiniZinc models
with verified solutions

Run MiniZinc and FlatZinc constraint models directly, with every solution re-verified. It is a newer Garmo Solvers module from the October 2026 benchmark campaign, outside the 1.0.2 release. Results are checked against the original input; the measured result below states where it is ahead and where it is not.

BUILT FOR

Constraint-programming, scheduling and planning teams with MiniZinc models.

YOUR CHALLENGE WITH MINIZINC

01

### The problem needs the right operation

A MiniZinc model and data, compiled to FlatZinc.

Run MiniZinc and FlatZinc constraint models directly, with every solution re-verified.

02

### A result must answer the original question

An answer detached from its original constraints or input is difficult to rely on.

The suite rechecks the answer against the original input and identifies the applicable result state.

03

### The comparison needs a defined scope

A capability or benchmark result is not a universal promise for a different workload.

Evaluate the selected input, resource budget, complete cost and required certificate against your baseline.

WHAT YOU GET

## A defined capability.
A useful result.

01

### Selected solving capability

Run MiniZinc and FlatZinc constraint models directly, with every solution re-verified.

02

### Original-input result

Solutions and objective values, each re-verified on the original model.

03

### Access by setup scope

Python API with headless execution today. garmo CLI and garmo-mcp setup is scoped on request; this publication does not invent executable commands or MCP tool names.

04

### Checked result

Every reported solution is re-verified on the original MiniZinc model.

GARMO SOLVERS / MEASURED RESULT

## Measured: 142 vs Chuffed 178 at 1200 s

On the 200 MiniZinc Challenge 2024 and 2025 instances at the 1,200 s challenge limit, with every solution re-verified against the original model: answers on 142, against 178 for Chuffed, 185 for CP-SAT and 145 for Gecode; proven optimal or infeasible on 37, against 93, 99 and 47. 0 rejected solutions.

EXAMPLE CUSTOMER WORKFLOW

## Use MiniZinc in a defined workflow

A customer has a supported model and wants an accepted result without adopting every other module.

Illustrative customer use—not a new benchmark or completed customer deployment.

1. 01

Provide the original input and define the useful outcome.

2. 02

Run the selected module under its supported resource and interface scope.

3. 03

Review the returned answer, original-input checks and completion state.

FIT & ACCEPTANCE

## Start with the task.
Agree the useful outcome.

What you bring

A MiniZinc model and data, compiled to FlatZinc.

What a useful evaluation measures

- + Accepted original-model result
- + Appropriate certificate or disclosed uncertified state
- + Total time, memory and operating cost

Delivery

License the selected capability, commission an implementation, or agree an operated service. Infrastructure and additional engineering are specified separately.

QUESTIONS BEFORE BUYING

## A clear scope.
A clear relationship.

**What is the important boundary? − **Chuffed, CP-SAT and Gecode answer more of the competition instances.

**How is it priced? + **$30,000 per year for the standalone module licence, for a named scope. The platform plans cover development use across the catalog; production rights for this module are part of the order.

**How do we get access? + **Python API with headless execution today. garmo CLI and garmo-mcp setup is scoped on request; this publication does not invent executable commands or MCP tool names.
