Deep neural network accelerated-group African vulture optimization algorithm for unit commitment considering uncertain wind power

L Yin, W Ding - Applied Soft Computing, 2024 - Elsevier
The unit commitment (UC) of power systems serves to plan out the starting and shutdown of
units and the power generation of units for a future period of time. However, the UC problem …

Analysis of the Lévy Flight Foraging Hypothesis in and Unreliability of the Most Rewarding Strategies

S Dipierro, G Giacomin, E Valdinoci - SIAM Journal on Applied Mathematics, 2023 - SIAM
We analyze the searching strategies of a forager diffusing in the whole space via an
