WebMay 15, 2024 · The use of simulated annealing (SA) (Kirkpatrick, Gelatt, & Vecchi, 1983) for timetabling problems dates back to the 1990s, with the pioneer proposals of Dowsland (1990) and Abramson (1991). In a later investigation, Thompson and Dowsland (1996) use SA to solve a variant of the ETP (a multi-objective formulation of the ETP). WebNov 19, 2024 · The simulated annealing algorithm requires that we track states (current, previous, best), which means we need to copy self.state frequently. Copying an object in Python is not always straightforward or performant. The standard library provides a copy.deepcopy () method to copy arbitrary python objects but it is very expensive.
