Perhaps you should try some spelling variations:
evolutionary algorithm » evolution algorithm, solution algorithm
positive evolutionary » objective evolutionary, positive solutions
allocation algorithm » estimation algorithm, evolution algorithm, predation algorithm
modified positive » modified passive, modified adaptive

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 objective allocation algorithm ) OR ( modified positive evolutionary algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective allocation algorithm ) OR ( modified positive evolutionary algorithm ))*.
