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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive evolutionary algorithms") or ("modified objective allocation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive evolutionary algorithms") OR ("modified objective allocation algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive evolutionary algorithms ) or ( modified objective allocation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive evolutionary algorithms") or ("modified objective allocation algorithm"))*.
