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 algorithm" » "modified nodal evolution algorithm", "modified nodal convolution algorithms", "modified nodal evolutionary algorithm", "modified adam solution algorithm", "modified near solution algorithm", "modified model solutions algorithm", "modified norway solution algorithm", "modified nacl solution 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: "((\"modified objective estimation algorithms\") OR (\"modified nodal solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified nodal solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified nodal solution algorithm"))*.
