Perhaps you should try some spelling variations:
"modified orcamplexity approximation algorithms" » "modified complexity approximation algorithms"
"modified nacl solution algorithm" » "modified nacl evolution algorithm", "modified nacl convolution algorithms", "modified nacl evolutionary algorithm", "modified male solution algorithm", "modified near solution algorithm", "modified orca solution algorithm", "modified exact solution algorithm", "modified nodal 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 nacl solution algorithm") OR ("modified orcamplexity approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified nacl solution algorithm\") OR (\"modified orcamplexity approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified nacl solution algorithm ) OR ( modified orcamplexity approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified nacl solution algorithm") OR ("modified orcamplexity approximation algorithms"))*.
