Query: Genetic Algorithms for Starshade Retargeting in Space-Based Telescopes   Future space-based telescopes will leverage starshades as components that can
be independently positioned. Starshades will adjust the light coming in from
exoplanet host stars and enhance the direct imaging of exoplanets and other
phenomena. In this context, scheduling of space-based telescope observations is
subject to a large number of dynamic constraints, including target
observability, fuel, and target priorities. We present an application of
genetic algorithm (GA) scheduling on this problem that not only takes physical
constraints into account, but also considers direct human suggestions on
schedules. By allowing direct suggestions on schedules, this type of heuristic
can capture the scheduling preferences and expertise of stakeholders without
the need to always formally codify such objectives. Additionally, this approach
allows schedules to be constructed from existing ones when scenarios change;
for example, this capability allows for optimization without the need to
recompute schedules from scratch after changes such as new discoveries or new
targets of opportunity. We developed a specific graph-traversal-based framework
upon which to apply GA for telescope scheduling, and use it to demonstrate the
convergence behavior of a particular implementation of GA. From this work,
difficulties with regards to assigning values to observational targets are also
noted, and recommendations are made for different scenarios.
