Perhaps you should try some spelling variations:
"modified positive evolutionary algorithm" » "modified positive evolution algorithm", "modified positive solution algorithm", "modified objective evolutionary algorithm", "modified positive solutions algorithm", "modified passive evolutionary algorithm", "modified adaptive evolutionary algorithm"
"modified _ optimisation algorithm" » "modified _ optimization algorithms", "modified _ estimation algorithm", "modified _ estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified positive evolutionary algorithm") or ("modified _ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified positive evolutionary algorithm") OR ("modified _ optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( modified positive evolutionary algorithm ) or ( modified _ optimisation algorithm ))*.
