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"
"powder using methods algorithm" » "powder nursing methods algorithm", "powder making methods algorithm", "powder counting methods algorithm", "code using methods algorithm", "boiler using methods algorithm", "model using methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network optimisation algorithm") or ("powder using methods algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimisation algorithm") OR ("powder using methods algorithm")).
• Removing quotes may allow a broader search: (( modified network optimisation algorithm ) or ( powder using methods algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithm") or ("powder using methods algorithm"))*.
