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