Perhaps you should try some spelling variations:
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified allocation optimized algorithms" » "modified allocation optimization algorithms", "modified allocation optimized algorithm", "modified allocation optimizer 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 allocation optimized algorithms") or ("modified objective evolutionary algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimized algorithms") OR ("modified objective evolutionary algorithm")).
• Removing quotes may allow a broader search: (( modified allocation optimized algorithms ) or ( modified objective evolutionary algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimized algorithms") or ("modified objective evolutionary algorithm"))*.
