According to the
object value in formulation (9), the number of seeds has a positive relationship with the
object value.
VRP, in which the multiple routes for a fleet of vehicles are determined for a set of customers to minimize the
object value, is a classical problem among many distribution problems.

%' shows the
object value of the best found solution, and the row 'Iter.' shows how many iterations were required to find this solution ('-' means that the best possible solution was not found).
Since JavaScript is a dynamic language, a variable holding a numeric value in one part of the code might be holding a string value in the next and an
Object value later on.
The updating policy will drive the particle swarm to move toward the region with higher
object value, and finally all particles will gather around the point with the highest
object value.
In other words, replacing an uninitialized
object value and the corresponding types with an initialized
object value and initialized object type does not affect the correspondence or whether the local variable y has the correct type.
