Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified orcad solution algorithm" » "modified orcad evolution algorithm", "modified orcad convolution algorithms", "modified orcad evolutionary algorithm", "modified orca solution algorithm", "modified norway 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 orcad solution algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified orcad solution algorithm\") OR (\"modified multiobjective optimizer algorithms\"))".
• Removing quotes may allow a broader search: (( modified orcad solution algorithm ) OR ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified orcad solution algorithm") OR ("modified multiobjective optimizer algorithms"))*.
