What Is OptaPlanner?
OptaPlanner is a constraint satisfaction solver framework for Java, developed by Red Hat. It uses mathematical optimization algorithms to find the best solution for a given problem, subject to a set of constraints, within a defined search space. OptaPlanner is designed to be used in planning and scheduling applications, such as resource allocation, workforce scheduling, and project planning.

What Are OptaPlanner Use Cases?
OptaPlanner is a constraint satisfaction solver that is used in a variety of use cases, including

1. Resource allocation: OptaPlanner can be used to allocate resources such as people, vehicles, and machines to tasks.
2. Scheduling: OptaPlanner can be used to schedule tasks such as employee shifts, appointments, and production runs.
3. Vehicle routing: OptaPlanner can be used to find the most efficient routes for vehicles, taking into account factors such as vehicle capacity, travel time, and delivery deadlines.
4. Staff rostering: OptaPlanner can be used to create fair and efficient schedules for employees, taking into account factors such as skill level, availability, and preferences.
5. Course scheduling: OptaPlanner can be used to schedule classes in a school or university, taking into account factors such as room capacity, teacher availability, and student preferences.
6. Supply chain optimization: OptaPlanner can be used to optimize supply chain operations, taking into account factors such as inventory levels, lead times, and transportation costs.
