TL;DR. A technique to reduce the search space in model checking or planning by exploiting the commutativity of concurrent transitions.
Technical Definition
A technique to reduce the search space in model checking or planning by exploiting the commutativity of concurrent transitions.
How it works
Partial order reduction is an optimization technique used in formal verification and automated planning. It aims to reduce the computational complexity by observing that certain concurrent actions can occur in different orders without changing the final state, thus pruning redundant search paths.
