OP System
Declarative governing equation specification compiler for structured dynamical systems. Transforms YAML model definitions into callable numerics.
OP System (Operator-Partitioned System) is a declarative specification compiler for structured dynamical systems. Users define governing equations, state variables, parameters, and operator partitions in YAML; the compiler transforms these into callable numerics consumed by OP Engine or other solvers.
The design eliminates the bookkeeping errors that arise when manually implementing large compartmental models (e.g., age-structured epidemic models with dozens of state variables) and reduces the barrier to simulation of complex structured models.
