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 method algorithm" » "model using mom algorithm", "model nursing methods algorithm", "model focusing method algorithm", "model using metal algorithm", "code using method algorithm", "models nursing method algorithm", "powder using method algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using method algorithm\") OR (\"modified network optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( model using method algorithm ) OR ( modified network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using method algorithm") OR ("modified network optimization algorithm"))*.
