Execution Tree Pruning

Execution tree pruning is an optimization technique used in formal analysis to discard irrelevant or redundant execution paths. By identifying paths that cannot lead to a vulnerability or that have already been analyzed, the tool can focus its computational power on more promising areas.

This is crucial for managing the state explosion problem in complex smart contracts. Pruning helps to significantly speed up the verification process without sacrificing accuracy.

It requires sophisticated algorithms to determine which branches can be safely ignored. This technique allows researchers to analyze larger and more complex systems that would otherwise be computationally impossible to verify.
