- Enable HybridProblem to create systems combining SDE and Jump processes - When SDE+Jump scales are present, returns JumpProblem wrapping SDEProblem - Merge has_sde && has_jump and has_jump branches into single has_jump block - Use mtkcompile for SDE+Jump (converts brownians → noise_eqs), complete for pure jump - Add comprehensive tests including mathematical correctness tests - Update HISTORY.md and docstrings with new functionality and correct solver (SRIW1) Co-Authored-By: Claude Opus 4.5 <[email protected]>
…Problem MTKBase now handles Symbol to Symbolic key conversion internally, so symmap_to_varmap is no longer needed for callback compilation. This simplifies the problem construction code. Co-Authored-By: Claude Opus 4.5 <[email protected]>
- Increase sample sizes to N=4000 for stronger statistical power - Test at 100 time points across transient dynamics (not just steady-state) - Add analytic transient mean validation: E[X](t) = k1/k2 + (X0 - k1/k2)*exp(-k2*t) - Add variance comparison between Catalyst and manual JumpProcesses implementations - Add complex non-linear multi-species test with bimolecular reactions (A + B -> C) - Fix ConstantRateJump -> VariableRateJump for rates depending on continuous dynamics - Add save_positions=(false,false) for efficiency with saveat - Use 5% relative tolerance for means, 10% for variances Co-Authored-By: Claude Opus 4.5 <[email protected]>
