Ant Colony Optimization algorithms were inspired by the foraging behavior of ants that accumulate pheromone trails on the shortest paths to food. Some ACO algorithms employ pheromone trail limits to improve exploration and avoid stagnation by ensuring a non-zero probability of selection for all trails. The MAX-MIN Ant System (MMAS) sets explicit pheromone trail limits while the Ant Colony Syste...
We present an algorithm for the quick delineation of capture zones using complex discharge potential. The flow is steady and two-dimensional in a homogeneous domain with anisotropic transmissivity. The procedure accommodates an arbitrary number of injection and extraction wells at any locations throughout the flowfield, as well as regional flow, in the form of a uniform flow component. Capture ...
An investigation was carried out for swirling flow in a rotating pipe with highly viscous fluid containing micro-bubbles experimentally and numerically. In the numerical analysis, bubble trajectory of each bubble was calculated using resultant numerical flow field solutions. From experimental results, with an aid of the numerical simulation, data were obtained for the location of a stagnation p...
Accomplishing useful tasks with a collection of decentralized mobile robots will require control methods that deal eeectively with a number of unique problems that impede the system's progress. Reactive control architectures can easily cause the problems of stagnation and cyclic behaviour , both characterized by a lack of progress in achieving a task. In this paper we present one possible solut...
We have used a soft-x-ray laser interferometer to study the collision and subsequent interaction of counterstreaming high-density plasmas. The measured density profiles show the evolution of the colliding plasmas from interpenetration, when the low-density edge of the plasmas first collide, to stagnation at the symmetry plane with density building at the symmetry plane. We compare the measured ...
