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"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder using methods 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: (("model using methods algorithm") OR ("modified network optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( model using methods algorithm ) or ( modified network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using methods algorithm") or ("modified network optimisation algorithm"))*.
