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 estimation algorithmss" » "modified based estimation algorithms", "modified based estimation algorithm", "modified based optimization algorithms", "modified pose estimation algorithmss", "modified based investigation algorithmss", "modified pulses estimation algorithmss", "modified male estimation algorithmss"

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