Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"modified d solution algorithm" » "modified d evolution algorithm", "modified d convolution algorithms", "modified d evolutionary algorithm", "modified df solution algorithm", "modified _ solution algorithm", "modified adam solution algorithm", "modified _ solutions algorithm", "modified drug solution 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 objective estimation algorithms") OR ("modified d solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified d solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified d solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified d solution algorithm"))*.
