Perhaps you should try some spelling variations:
approximation algorithm » approximation algorithms
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
invasive evolution » invasive ventilation
modified invasive » modified passive
one approximation » time approximation, _ approximation, rough approximations
modified one » modified male, modified near, modified orca

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified invasive evolution algorithm ) OR ( modified one approximation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified invasive evolution algorithm ) OR ( modified one approximation algorithm ))*.
