**PSO** can behave drastically differently depending on these coefficients. The upper bound of the velocity v max can also lead to problems if a fixed value is posited. There is no rule of thumb for setting it as the value is usually problem-specific. Further, when the upper bound is used in the **algorithm**, the particle’s trajectory fails to converge..
