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"
"modified df solution algorithm" » "modified df evolution algorithm", "modified df convolution algorithms", "modified df evolutionary algorithm", "modified _ solution algorithm", "modified adam solution algorithm", "modified bi1 solution algorithm", "modified drug solution algorithm", "modified up solutions 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 df solution algorithm") OR ("modified network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df solution algorithm\") OR (\"modified network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified df solution algorithm ) OR ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df solution algorithm") OR ("modified network optimisation algorithm"))*.
