JAS-mine maintains and develops the JAS simulation platform, a discrete-event tool-kit for agent-based and dynamic microsimulation modelling. This repository contains the core libraries. See www.jas-mine.net for more details.
SimulationEngine.getRnd().nextDouble() generates numbers in [0, 1), not in [0, 1], which is not suitable for probabilities.
This affects at least AbstractSortByDifferenceAlignment.
UPD. SBDLAlignment relies on the values, provided by this rng. Since the formula used is log(1 / r - 1) we potentially get division by zero or cases of log(0).
