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