quantum_launcher.problems.problem_initialization.ec

This module contains the EC class.

Summary

Classes:

EC	Class for exact cover problem.

Reference

class quantum_launcher.problems.problem_initialization.ec.EC(instance: List[Set[int]] = None, instance_name: str = 'unnamed')

Bases: Problem

Class for exact cover problem.

The exact cover problem is a combinatorial optimization problem that involves finding a subset of a given set of elements such that the subset covers all elements and the number of elements in the subset is minimized. The class contains an instance of the problem, so it can be passed into Quantum Launcher.

onehot

The one-hot encoding used for the problem.
