Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
evolutionary algorithm » evolution algorithm, solution algorithm
network optimisation » network optimization
modified network » certified network, defined network, modified near
modified drug » modified df, 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 network optimisation algorithm ) OR ( modified drug evolutionary algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified network optimisation algorithm ) OR ( modified drug evolutionary algorithm ))*.
