Perhaps you should try some spelling variations:
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
time approximation » one approximation, _ approximation
modified time » modified bi1, modified male
modified a » modified _, modified df, modified adam
a solution » _ solution, _ solutions, 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 time approximation algorithms ) OR ( modified a solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified time approximation algorithms ) or ( modified a solution algorithm ))*.
