Learning to Generalize Across Conditions: A PPO-Based Learning Approach to Multi-Condition Multi-Objective Optimization

This study introduces sPPO-CR, a policy-gradient deep reinforcement learning (DRL) algorithm for multi-objective (MO) and multi-condition multi-objective (MCMO) optimization. The method builds on a simplified single-step variant of Proximal Policy Optimization (PPO) and incorpora...

Evanescent Bloch wave framework for water-wave propagation through an array of porous structures

Abstract We present a theoretical framework for water-wave interaction with finite periodic arrays of porous blocks, with emphasis on the effect of dissipation on the complex band diagram of the media. A semi-analytical model based on linear potential-flow theory, coupled with po...
