Path Explosion Problem
The path explosion problem is a significant challenge in symbolic execution where the number of possible execution paths in a program grows exponentially with the number of branches. This makes it computationally infeasible to explore all paths in large or complex smart contracts.
To manage this, researchers use techniques like path pruning, search heuristics, and state merging to focus on the most relevant areas of the code. This is a critical limitation that developers must navigate when using automated analysis tools.
It highlights the need for modular code design and efficient analysis strategies. Understanding this problem is key to effectively using modern security tooling.
It represents the fundamental trade-off between coverage and performance in automated testing.
