Perhaps you should try some spelling variations:
approximations algorithms » approximation algorithms, approximation algorithm
rough approximations » one approximation
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
adaptive evolution » adaptive ventilation
modified adaptive » modified passive

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified rough approximations algorithms ) OR ( modified adaptive evolution algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified rough approximations algorithms ) OR ( modified adaptive evolution algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified rough approximations algorithms ) OR ( modified adaptive evolution algorithm ))*.
