Perhaps you should try some spelling variations:
"certified network optimization algorithm" » "certified network optimization algorithms", "certified network optimisation algorithm", "certified network estimation algorithm", "verified network optimization 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("model using methods algorithm") OR ("certified network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using methods algorithm\") OR (\"certified network optimization algorithm\"))".
• Removing quotes may allow a broader search: (( model using methods algorithm ) OR ( certified network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("model using methods algorithm") OR ("certified network optimization algorithm"))*.
