Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
adam optimization » game optimization, stage optimization, _ optimization
method algorithm » mom algorithm
modified adam » modified df, modified near
model using » models nursing, powder using

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: (( ((model using) OR (code using)) method algorithm ) OR ( modified adam optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((model using) OR (code using)) method algorithm ) or ( modified adam optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((model using) OR (code using)) method algorithm ) or ( modified adam optimization algorithm ))*.
