lastAcceptanceProbability

Tracks the last computed acceptance probability in the simulated annealing process.

This value represents the probability of accepting a new solution during the most recent iteration of the algorithm, based on the current temperature and the difference in cost between the current and new solutions. It is initially set to 1.0 and is updated internally during each iteration.

The property is immutable from outside the class to ensure the integrity of the algorithm's state. It serves as a diagnostic tool for understanding the behavior of the acceptance step in the optimization process.
