NEWS ABSTRACT10/22/2026 · one shared analysis
The paper argues that a useful symbol for hybrid discrete-continuous robot planning is one that exposes the discrete commitments simplifying the underlying planning problem for the solver. It introduces solver-sufficient symbolization, characterized precisely for finite-horizon piecewise-affine systems, and a counterexample-guided algorithm for symbol invention. The approach is extended to optimization objectives parameterized by neural networks as energy functions, with symbols induced from continuous optimization landscapes. Reported experiments on simulated and real-robot tasks indicate reduced solving cost, preserved solution quality, and improved interpretability and steerability.
Why it matters
It offers a computational criterion for choosing symbols in robot planning, rather than relying on human-defined or language-derived sets, and may explain why certain human symbols work well.
