Is there an ideal ratio between a training set and validation set? Which trade-off would you suggest?

I have studying the size of my training sets. I am wondering if there is an "ideal" size or rules that can be applied. I am thinking of a generative hyper-heuristics that aim at solving np-hard...

In online machine learning, is the effectiveness of the learning mechanism measured?

In an online machine learning, the learning mechanism evolves at the same time as the method solution. It is hope the learning mechanism adapts to the search. Could somebody be kind enough to...

Hyper-heuristics, Programming by Optimisation, Machine learning, Genetic Improvements. Is there a clear difference between them?

I often come across these four paradigms. The more I look into the literature, the more I notice they appear to have same goal (i.e. searching the algorithm space to find or improve on a solver)....

From Wirth's work, it is suggested that an iteration is a form recursion; a finite recursive process. Is it a form of recurrence?

To the best of my knowledge, in mathematics, a recurrence defines a recursive sequence. In computer science, an application of recursion appears to be a loop structure in a programming language...

The Lin-Kernighan method can solve the TSP in polynomial time complexity. Would an Iterative Lin-Kernighan (or other ILS) reduce this measurement?

I am having some difficulties to find in a literature some establish time complexity for the ILS and TSP. Does anybody can help, please.

Is anybody aware how GP could encode iterations and conditions operators?

I am looking to extend my functions with iterations and conditions. The algorithms I am thinking to generates would use both of them. I can only appreciate how challenging it can be. Has anybody...

Is it possible to consider the iterated local search as a special memetic algorithm?

I have been looking at iterated local search and memetic algorithm recently. Both algorithms have some form of perturbations and apply a local search. It appears that pattern is present in both...

Should we compare the performance of a generative hyper-heuristics against an exhaustive search?

Let's imagine a generative hyper-heuristics generates very short metaheuristics. No limitation of the length of the algorithms has been given in some inductive bias. Is it really necessary to...
