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