Conflict Resolution of Cluttered Multi-robot Systems Using Metaheuristic Optimization Algorithms
Bibliographic record
Abstract
Conflict resolution becomes crucial when one is dealing with a large number of robots working in cluttered environments. The majority of the developed conflict resolution approaches in the literature deal with a motion-liveness problem which fails to gain collision-free movements for a large number of robots. This paper develops a systematic approach for coordinating the motions of multi-robot systems by adjusting their speeds to avoid collisions and guarantee motion-liveness of the robots. We mathematically formulate the multi-robot motion as a constrained optimization problem to minimize the time it takes for each robot to reach its target while avoiding collisions. Using two metaheuristic optimization methods, multiobjective genetic algorithm and particle swarm optimization, we can solve the conflict resolution problem up to 30 robots in a highly cluttered environment. Results show that we can find collision-free movements for a large number of robots in cluttered environments, while also guaranteeing multi-robot motion-liveness.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
