Preparing for the Unexpected: Diversity Improves Planning Resilience in Evolutionary Algorithms
[article]
2018
pre-print
Preserved Fulltext
As an example case, we implement a diversity-aware genetic algorithm using two different metrics for diversity (differing in their generality) and show that the blow in performance due to unexpected change ...
In order to improve the planner's resilience to unforeseen change, we argue that maintaining a certain level of diversity amongst the considered plans at all times should be added to the planner's objective ...
