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