This study addresses the distributed optimization problem with time-varying objective functions and constraints in a multi-agent system (MAS). To tackle constrained (DTVCO) problem, each agent MAS communicates its neighbors while relying solely on local information, such as own function constraints, to compute optimal solution. We propose novel penalty-based zeroing neural network (PB-ZNN) solve continuous-time DTVCO (CTDTVCO) problem. The PB-ZNN model incorporates two penalty functions:...
