Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified orca evolutionary algorithm" » "modified orca evolution algorithm", "modified orca solution algorithm", "modified dorca evolutionary algorithm", "modified orcad evolutionary algorithm", "modified ohca evolutionary 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 orca evolutionary algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified orca evolutionary algorithm\") OR (\"modified notion optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified orca evolutionary algorithm ) OR ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified orca evolutionary algorithm") OR ("modified notion optimization algorithms"))*.
