'''Frozen variables''' are variables in a [[constraint satisfaction]] problem that are locked into a single value across all solutions within a given cluster of the [[solution space]]. Unlike variables in the [[backbone of satisfiability]] — which are fixed across all solutions globally — frozen variables are fixed only within a local cluster. Different clusters may freeze the same variable to different values, creating barriers that local search algorithms cannot cross.

The phenomenon of freezing is central to understanding [[algorithmic phase transition|algorithmic phase transitions]]. As a problem approaches the critical threshold, the fraction of frozen variables increases rapidly, and the solution space shatters into clusters separated by Hamming deserts where no valid solutions exist. An algorithm that begins its search in one cluster and makes a wrong early assignment to a frozen variable will expend exponential time exploring a dead end. The freezing transition — the point at which frozen variables first appear — is a precise predictor of where simple algorithms fail and where more sophisticated methods become necessary.
