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