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