Perhaps you should try some spelling variations:
parameter optimized » parameter optimization
optimized algorithm » optimized algorithms, optimizer algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified co » modified _, modified df, modified orca
co solution » co evolution, _ solution, nacl solution

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 co solution algorithm ) OR ( modified parameter optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified co solution algorithm ) or ( modified parameter optimized algorithm ))*.
