Perhaps you should try some spelling variations:
"modified stochastic optimisation algorithms" » "modified stochastic optimization algorithms", "modified static optimization algorithms", "modified stochastic configuration algorithms", "modified stochastic optimisation algorithm", "modified stochastic estimation algorithms"
"modified objective predators algorithm" » "modified objective predation algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified stochastic optimisation algorithms\") OR (\"modified objective predators algorithm\"))~".
• Removing quotes may allow a broader search: (( modified stochastic optimisation algorithms ) OR ( modified objective predators algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimisation algorithms") OR ("modified objective predators algorithm"))*.
