A Composite Service Provisioning Mechanism in Edge Computing

Algorithm 3

The algorithm for users who need to reuse optimized intermediate solution.

(1)	Input: the QoS of component service after the deployment location changes
(2)	Output: the optimized intermediate solution obtained in limited time
(3)	Run Algorithm 2 to select reused optimized intermediate solutions for user;
(4)	= 0; \\The variable is initialized to zero
(5)	Read three probability models of sub-population from memory space, and obtain ;
(6)	The remaining steps are the same as lines 8–16 of Algorithm 1;
