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