An Adaptive Multiexecutors Scheduling Algorithm Based on Heterogeneity for Cyberspace Mimic Defense

Algorithm 1

Heterogeneous measure algorithm based on VTG (HTVG).

	Assumption: The relationship of vulnerabilities and components between executors have been found;
	Input: The relationship of vulnerabilities and components between executors
	Output: Heterogeneity of executor set
