Abstract

fetched live from OpenAlex

We proposed in a previous paper a hybrid technique, combining local steering behaviors and coordination graphs (CG), that allows real-time motion planning of multiple agents in a narrow passage. This hybrid technique not only avoids deadlocks, but also exhibits other interesting behaviors such as leader following, even though they are not explicitly coded in the algorithm. In this paper, we build upon the earlier result, and propose a two-layered approach to motion planning of multiple agents in virtual environments, consisting of open spaces connected by multiple narrow passages. The discrete generalized Voronoi diagram (GVD) of the static environment is used to identify all narrow passages automatically. The global path of each agent is also planned using the GVD. As each agent moves along its global path, it is locally modified using the hybrid technique combining steering behaviors with coordination graphs. Experimental results show that the resulting planner is able to plan motions of 30 agents in a virtual environment with three narrow passages in real-time, and the pre-processing phase of our approach is extremely fast. Since all planning is done in real-time, the approach allows an agent to change its final destination at runtime

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
