Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"modified caging prediction algorithm" » "modified caging predation algorithm", "modified caging predators algorithm", "modified learning prediction algorithm", "modified churn prediction algorithm", "modified cliff prediction 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 prediction algorithm") or ("modified network optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging prediction algorithm") OR ("modified network optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified caging prediction algorithm ) or ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging prediction algorithm") or ("modified network optimisation algorithm"))*.
