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