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 based optimized algorithms" » "modified based optimized algorithm", "modified based optimizer algorithms", "modified based optimization algorithms", "modified male optimized algorithms"

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