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 algorithm", "modified stochastic estimation algorithms"
"modified arcad predation algorithm" » "modified arcad predators algorithm", "modified arcad estimation algorithm", "modified orca predation algorithm", "modified adam predation 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 arcad predation algorithm") or ("modified stochastic optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified arcad predation algorithm") OR ("modified stochastic optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified arcad predation algorithm ) or ( modified stochastic optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified arcad predation algorithm") or ("modified stochastic optimisation algorithm"))*.
