How to generate instances with relevant properties and without bias remains an open problem of critical importance to compare heuristics fairly. When scheduling with precedence constraints, the instance is a task graph that determines a partial order on task executions. To avoid selecting instances among a set populated mainly with trivial ones, we rely on properties such as the mass, which measures how much a task graph can be decomposed into smaller ones. This property and an in-depth analysis of existing random instance generators establish the sub-exponential generic time complexity of the studied problem.
