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