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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( 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 ))*.
