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 nodal solution algorithms" » "modified nodal solution algorithm", "modified nodal evolution algorithm", "modified nodal convolution algorithms", "modified adam solution algorithms", "modified near solution algorithms", "modified model solutions algorithms", "modified norway solution algorithms", "modified nacl solution algorithms"

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 nodal solution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified nodal solution algorithms\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified nodal solution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified nodal solution algorithms"))*.
