Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
trained solution » saline solution
coarse trained » coarse grained, coarse grain
parameter » parameters

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: (( coarse trained solution algorithm ) OR ( modified parameter optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( coarse trained solution algorithm ) or ( modified parameter optimization algorithms ))*.
