Timileyin Okoya, Waliu Apena, Folasade Dahunsi, Olufunso Alowolodu . Review of Decentralized Reinforcement Learning for Multi-Agent Robotic Task Scheduling. International Journal of Computer Applications. 187, 149 ( Oct 2026), 18-25. DOI=10.5120/ijca28de3ec5ef45
Multi-robot task scheduling is fundamental to managing multi-agent robotic systems (MARS) in unpredictable environments such as logistics, disaster management and autonomous exploration. Centralized task allocation scales poorly and adapts slowly to change, and reinforcement learning (RL) offers an alternative in which robots learn scheduling strategies through interaction. This review analyses 75 studies on multi-agent task allocation with RL, with particular attention to PettingZoo’s Pistonball environment as a multi-agent RL (MARL) benchmark. It combines a bibliometric profile of the corpus, a side-by-side comparison of representative studies, a qualitative comparison of learning paradigms and a graded appraisal of the evidence behind five recurring claims. Fully decentralized learning remains difficult because concurrent policy updates produce non-stationarity, whereas centralized training with decentralized execution (CTDE) has proved more practicable; hardware-validated schedulers are the weakest-supported area. The review identifies the need for systematic comparison of CTDE-based algorithms for vision-based multi-robot task scheduling under identical conditions in the Pistonball environment.
