Nan or inf prevents convergence
Witryna13 lip 2013 · inf is infinity - a value that is greater than any other value. -inf is therefore smaller than any other value. nan stands for Not A Number, and this is not equal to 0. Although positive and negative infinity can be said to be symmetric about 0, the same can be said for any value n, meaning that the result of adding the two yields nan.

Recall that some … WitrynaAirport gate assignment is a critical issue in airport operations management. However, limited airport parking spaces and rising fuel costs have caused serious issues with gate assignment. In this paper, an effective multiobjective optimisation model for gate assignment is proposed, with the optimisation objectives of minimising real-time flight …
