The liquid cargo replenishment decision based on ship’s stability, strength and the floating state is a multiobjective optimization problem. The mathematical model of multi-objective is built in this paper. Aiming to obtain the feasible solution, the adaptive step ergodic of permutation and combination is applied in terms of the cargo oil tank and the water ballast tank. particle swarm optimiza...

Computational models of cognition provide an interface to connect advanced mathematical tools and methods to empirically supported theories of behavior in psychology, cognitive science, and neuroscience. In this article, we consider a computational model of instance-based learning, implemented in the ACT-R cognitive architecture. We propose an approach for obtaining mathematical reformulations ...

Utilizing exoskeleton devices to help elderly or empower workers is a growing field of research in robotics. The structure an can vary depending on user’s physical dimensions, joints muscles targeted for assistance, and maximum achievable actuator torque. In this research, Human-Model-In-the-Loop (HMIL) constrained optimization technique proposed design the RoboWalk lower-limb exoskeleton. unde...

In this work, we perform an extensive theoretical and experimental analysis of the characteristics five most prominent algebraic modelling languages (AMPL, AIMMS, GAMS, JuMP, Pyomo) systems supporting them. our comparison, evaluate how reviewed modern match current requirements. analysis, use a purpose-built test model library to benchmarks. We provide insights on which performed best features ...
