Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near 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"

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