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