OMNISIM is a simulation and prediction platform built on multi-agent swarm modeling. Instead of running a single scenario, it spins up populations of interacting agents across a chosen domain — epidemiology, financial markets, political systems, or biological processes — and lets them evolve according to configurable rules. The engine then identifies which outcomes are mathematically optimal given the constraints you set. Useful for researchers stress-testing policy decisions, analysts modeling market dynamics under uncertainty, or curious users exploring counterfactuals ('what if this pathogen had a 10% higher transmission rate?'). The swarm approach captures emergent behavior that single-variable models miss, making it more realistic for complex adaptive systems.
