Perhaps you should try some spelling variations:
convolutional algorithms » convolution algorithms, evolution algorithm, evolutionary algorithm
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
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 optimisation algorithm ) OR ( modified d convolutional algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) or ( modified d convolutional algorithms ))*.
