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

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