About the publication

The paper addresses a novel approach to imaging in radio astronomy, a complex inverse problem. Where traditionally, multi-criteria (or multi-objective) optimization has been used together with genetic algorithms to convert telescope data into a set of images more quickly and cheaply.

The research proposes a multi-objective optimization problem together with genetic algorithms to obtain a set of black hole images, taking into account technological limitations.

On the other hand, they have applied artificial intelligence to group the solutions into groups (clusters) and have automated the choice of the “best” photograph in an agnostic manner.

Thanks to multi-objective optimization and genetic algorithms, images can be reconstructed without losing quality and with a reduction in the computing costs necessary to obtain them. Likewise, the flexibility of genetic algorithms and multi-criteria optimization takes on special relevance when the problems are highly complex, involving numerous variables with many decisions that cannot be related to each other in a simple way, or that could even seem contradictory.
