Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"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.

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