Perhaps you should try some spelling variations:
"modified deep evolutionary algorithm" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified delphi evolutionary algorithm", "modified df evolutionary algorithm", "modified near evolutionary algorithm"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

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

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