Perhaps you should try some spelling variations:
convolutional algorithms » convolution algorithms, evolution algorithm, evolutionary algorithm
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
d convolutional » deep convolutional
modified d » modified df, modified _, modified adam

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified objective optimization algorithm ) OR ( modified d convolutional algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified objective optimization algorithm ) OR ( modified d convolutional algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimization algorithm ) OR ( modified d convolutional algorithms ))*.
