Weak Form Recovery of Heston Type Stochastic Dynamics
Sai Sathvik Gullipalli, Eshwar R A, Gajanan V. Honnavar
Estimating the coupled drift, diffusion, and leverage structure of a stochastic-volatility model directly from a price path is an unresolved inverse problem: Kramers--Moyal increme…

Data-Driven Weak-form Discovery of Stochastic Systems
Eshwar R A, Gajanan V. Honnavar
We present an algorithm for learning the governing equations of a stochastic dynamical system from trajectory data. It recovers interpretable symbolic expressions for both the drif…

Yukthi Opus: A Multi-Chain Hybrid Metaheuristic for Large-Scale NP-Hard Optimization
SB Danush Vikraman, Hannah Abigail, Prasanna Kesavraj +1
We present Yukthi Opus (YO), a multi-chain hybrid metaheuristic designed for NP-hard optimization under explicit evaluation budget constraints. YO integrates three complementary me…
