14 A particle moves in a straight line from a fixed point O. Its velocity, v ms', is given by v= 4t(4 - t), where t is the time, in seconds, after leaving the point O. Find(a) the maximum velocity of the particle,[3 marks](b) the displacement of the particle at t = 5...
Another challenge for one using PSO is how to handle the bounds of the search domain whenever a particle moves beyond it. Many popular strategies that had already been proposed are reviewed and compared for PSO classical version in [23]. Those strategies may be reviewed and understood by PSO ...
