Perhaps you should try some spelling variations:
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"
"modified caging predation algorithm" » "modified caging predators algorithm", "modified caging estimation algorithm", "modified aging predation algorithm", "modified changing predation algorithm", "modified charging 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 caging predation algorithm") OR ("modified static optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified caging predation algorithm ) or ( modified static optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging predation algorithm") or ("modified static optimization algorithm"))*.
