Perhaps you should try some spelling variations:
convolutional algorithm » convolution algorithms, evolution algorithm, evolutionary algorithm
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
trained convolutional » graph convolutional
coarse trained » coarse grained, coarse grain

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified multiobjective optimization algorithm ) or ( coarse trained convolutional algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified multiobjective optimization algorithm ) OR ( coarse trained convolutional algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimization algorithm ) or ( coarse trained convolutional algorithm ))*.
