n September 24, 2026, Iain Morrow, a mathematician and modeler, presented his freely available program JuCIB. JuCIB, written in the Julia programming language, combines several programming techniques, thereby enabling the solution of very large and, above all, dense CIB matrices up to 1,000–5,000 times faster than before. This now makes it possible for the first time to fully scan even large matrices (over 50 descriptors) for consistent scenarios. JuCIB also enables the rapid analysis of attractor basins (scenario weights in ScenarioWizard) for matrices up to approximately 6 million solutions in size. The community is enthusiastic about this new approach, which opens up new evaluation possibilities for the first time, particularly for large multi-level matrices and large AI-generated matrices.
