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