Is it possible to train a neural network to solve NP-complete problems?

I’m sorry if the question is not relevant, i have tried to search for articles about it but i couldn’t find satisfying answers.

I’m starting to learn about machine learning, neural networks etc … and i was wondering if making a neural network that takes a graph as input, and output the answer of an np-complete problem (e.g. the graph is hamiltonian / the graph has independant set superior to k, and other decision problems) would work ?

I haven’t heard of any np complete problems being solved like this, so i guess it does not work, are there theoretical results stating that a neural network cannot learn np-complete language or something like this ?
