PHCpack :: randomSeed

randomSeed -- seed for the random number generators

Description

To avoid singularities during complex path following, the homotopy methods use a random constant. Different runs with solveSystem, trackPaths, or mixedVolume (with StartSystem set to true) may therefore lead to the solutions listed in a different order. Fixing the value of randomSeed leads to reproducible runs.
