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