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).
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.
