Colonial competitive evolutionary Rao algorithm for optimal engineering design

AEJ - Alexandria Engineering Journal, 2022
Rao algorithms that include three algorithms are very simple and parameter-less algorithms with effective and desirable performance. This paper modifies these three algorithms, merges them, and establishes a powerful group algorithm.

Passive MIMO radar detection in the presence of clutter or multi‐path without reference channel

IET Radar, Sonar & Navigation, 2021
Target detection problem in a multiple‐input multiple‐output (MIMO) radar which includes non‐cooperative illuminators of opportunity (IOs) and spatially distributed receivers is discussed. The receivers utilize only one processing channel and discard the

A Modified Rao-2 Algorithm for Optimal Power Flow Incorporating Renewable Energy Sources

Mathematics, 2021
In this paper, a modified Rao-2 (MRao-2) algorithm is proposed to solve the problem of optimal power flow (OPF) in a power system incorporating renewable energy sources (RES). Quasi-oppositional and Levy flight methods are used to improve the performance
