GeoNest framework enhances packing efficiency using reinforcement learning

Researchers have developed GeoNest, a novel framework for the two-dimensional irregular knapsack problem within a circular container. This problem is crucial for maximizing material utilization in manufacturing. GeoNest employs a graph policy trained via reinforcement learning to identify and select optimal neighborhoods for packing polygons, addressing the issue of residual space being partitioned into unusable small pockets. The framework improves mean utilization by approximately 0.6% to 0.9% over existing state-of-the-art solvers, as demonstrated on a new benchmark called CircleNest-Bench. AI
