Create a section Nav > Our Mission

• Why we made this app
• Outline our goals
  • give exposure to MAPF and a topic of discussion and share ongoing research efforts
  • introducing CBS to those outside the MAPF community
  • to make state-of-the-art (recent unlike most algorithms learned by new students like standard A* which was developed in 1968) developments more accessible by introducing them outside of academic journals (or upper-division AI courses), on an easy-to-digestible platform
  • contribute efforts in making MAPF accessible and easier for new students to visualize the algorithms
