Here, we investigate the classical p-median location problem on a network in which the vertex weights and the distances between vertices are uncertain. We propose a programming model for the uncertain p-median location problem with tail value at risk objective. Then, we show that it is NP-hard. Therefore, a novel hybrid modified binary particle swarm optimization algorithm is presented to obtai...

This paper presents and experimentally implements three different adaptive robust controllers as the first steps toward using model-based for transfemoral prostheses. The goal of this is to translate these control methods robotic domain, from bipedal walking prosthesis walking, including a rigorous stability analysis. human/prosthesis system modeled two-domain hybrid asymmetric system. An optim...

One of the major puzzles in performing multi-agent-based simulations is the validity of their results. Optimisation of simulation parameters can lead to results that can be deceitful, optimistic, or plainly wrong. When the issue at stake is inherently complex, which is frequently the case with social phenomena, the search for emergent outcomes is closely related to macro effects deriving from m...
