Abstract

fetched live from OpenAlex

The authors describe a heuristic technique for solving the problem of path planning based on local information for a mobile robot with acceleration constraints moving amidst a set of stationary obstacles. The concept of safety is introduced to design a planning strategy. A path which maximizes the product of safety based on local information and attraction towards the goal is chosen. The safety function depends on the acceleration bounds. The attraction toward the goal depends on the distance from the goal. Two additional heuristics are proposed to improve the efficiency of the search process and to enhance the ability of the robot to avoid obstacles. Some simulation examples of the algorithm corresponding to different navigational environments are discussed.>

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
