Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified model predation algorithm" » "modified model predators algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified model predictive algorithm", "modified model predicting algorithm", "modified male predation algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified model predation algorithm") OR ("modified notion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified model predation algorithm ) or ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified model predation algorithm") or ("modified notion optimization algorithms"))*.
