Root cause analysis is augmented by providing optimized inputs to root cause analysis systems or the like. Such optimized inputs can be generated from causality graphs by creating sub-graphs, finding and removing cycles, and reducing the complexity of the input. Optimization of inputs enables a root cause analysis system to reduce the number of iterative cycles that are required to execute probable cause analysis, among other things. In one instance, cycle removal eliminates perpetuation of errors throughout a system being analyzed.
