evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
one approximation » time approximation, _ approximation, rough approximations
modified one » modified male, modified near, modified orca
discursive » dispersive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified one approximation algorithm ) or ( modified discursive evolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified one approximation algorithm ) OR ( modified discursive evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified one approximation algorithm ) or ( modified discursive evolution algorithm ))*.
