{
Velocity velocity;
for (int i = 0; i < currentProblem->n; ++i) {
double randomVariable = getRandomDoubleValue(0.0, 1.0);
velocity.push_back(randomVariable);
}
return velocity;
}示例2: findSolution
void Solver::findSolution()
{
for (auto &i : swarm.getParticles()) {
Velocity newVelocity;
Solution newPosition;

* Iterate through all dimensions of a Solution/position
* to calculate the new velocity and update the position.
*
* j = dimension
