Perhaps you should try some spelling variations:
"modified caging optimisation algorithms" » "modified caging optimisation algorithm", "modified caging optimization algorithms", "modified caging estimation algorithms", "modified staffing optimization algorithms"
"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"

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 network optimization algorithm") OR ("modified caging optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) or ( modified caging optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") or ("modified caging optimisation algorithms"))*.
