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