abstract = "The uncertain capacitated arc routing problem is of
great significance for its wide applications in the
real world. In uncertain capacitated arc routing
problem, variables such as task demands and travel
costs are realised in real time. This may cause the
predefined solution to become ineffective and/or
infeasible. There are two main challenges in solving
this problem. One is to obtain a high-quality and
robust baseline task sequence, and the other is to
design an effective recourse policy to adjust the
baseline task sequence when it becomes infeasible
and/or ineffective during the execution. Existing
studies typically only tackle one challenge (the other
being addressed using a naive strategy). No existing
work optimises the baseline task sequence and recourse
policy simultaneously. To fill this gap, we propose a
novel proactive-reactive approach, which represents a
solution as a baseline task sequence and a recourse
policy. The two components are optimised under a
cooperative co-evol",
