Potential heuristics for state-space search are defined as weighted sums over simple state features.

Iterative Budgeted Exponential Search

no code implementations30 Jul 2019 Malte Helmert, Tor Lattimore, Levi H. S. Lelis, Laurent Orseau, Nathan R. Sturtevant

For graph search, A* can require $\Omega(2^{n})$ expansions, where $n$ is the number of states within the final $f$ bound.

Exponential-Binary State-Space Search
