Partner Units Polynomial

Problem description

Partner unit problem describes a people counting system.

The problem includes three types of components, namely a door sensor, a zone and a communication unit. The problem requirements are:

1. Each zone as well as each door sensor must be connected to exactly one unit;
2. Each unit can control at most two door sensors and at most two zones;
3. If a unit controls a door sensor that contributes to a zone controlled by another unit, then the two units must be connected directly, i.e. one unit becomes a partner unit of the other and vice versa;
4. Each unit can have at most maxPU partner units which is constant for each problem instance.

The solution of the partner unit problem is defined as follows:

• Given a consistent configuration of door sensors and zones, a number of available units lower and a constant maxPU, find a valid assignment of units that satisfies all requirements.
