Perhaps you should try some spelling variations:
"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"
"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 ("modified network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using methods algorithm\") OR (\"modified network optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( model using methods algorithm ) OR ( modified network optimization algorithm ))*.
