libMultiRobotPlanning

libMultiRobotPlanning is a library with search algorithms primarily for task and path planning for multi robot/agent systems. It is written in C++(14), highly templated for good performance, and comes with useful examples.

The following algorithms are currently supported:

• Single-Robot Algorithms

  • A*
  • A* epsilon (also known as focal search)
  • SIPP (Safe Interval Path Planning)

• Multi-Robot Algorithms

  • Conflict-Based Search (CBS)
  • Enhanced Conflict-Based Search (ECBS)
  • Conflict-Based Search with Optimal Task Assignment (CBS-TA)
  • Enhanced Conflict-Based Search with Optimal Task Assignment (ECBS-TA)
  • Prioritized Planning using SIPP (example code for SIPP)

• Assignment Algorithms

  • Minimum sum-of-cost (flow-based; integer costs; any number of agents/tasks)
  • Best Next Assignment (series of optimal solutions)
