algorithms (e.g., [1], [2]), continuous-time -agentsolvers have recently been applied to distributed optimization problems as a promising and useful technique [3]–[8], thanks to the well-developed continuous-time stability theory. Constrained distributed optimization, in which the feasible solutions are limited to a certain

Soccer games optimization is a new metaheuristics method that mimics the soccer player's movement, wherein each player decides their best positions to dribble the ball towards the goal based on the ball position and other players' position. This paper discussed the method for continuous .

As long as your require the radius of the ball to be strictly positive note that closed balls contain open balls, so the requirement for "open balls" is satisfied. Generally, however, the topological definition for a continuous map is "the preimage of an open set is open".

[PDF] - Oracle® Crystal Ball Decision Optimizer, Fusion Edition
Welcome to OptQuest, an optimization option available in Oracle Crystal Ball Decision Optimizer, Fusion Edition. OptQuest enhances Crystal Ball by automatically searching for and finding optimal solutions to simulation models. Simulation models by themselves can only give you a range of possible outcomes for any situation.

[PDF] - Oracle Crystal Ball and OptQuest (Decision Optimizer)
Decision Optimizer (OptQuest) is an optimization tool that runs as an add-in to Crystal Ball that enhances simulation models by automatically searching for and finding optimal solutions. At the basic level, OptQuest selects a value for each decision variable, enters those values into your spreadsheet, runs a Monte Carlo simulation on the spreadsheet, records the results, and repeats the process.

The ball charge grading used during most of the test runs was an industrial standard grading with balls between 12 and 20 mm. The average ball diameter was 15.8 mm; the average ball weight was 15.3 g/piece. For the experiments in which a finer ball grading was used a bored discharge diaphragm (bore hole diameter: 4 mm) was built in.
