Perhaps you should try some spelling variations:
"modified dorcadmplexity approximation algorithms" » "modified complexity approximation algorithms"
"modified exact solution algorithms" » "modified exact solution algorithm", "modified exact evolution algorithm", "modified exact convolution algorithms", "modified nacl solution algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified exact solution algorithms") or ("modified dorcadmplexity approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified exact solution algorithms") OR ("modified dorcadmplexity approximation algorithms")).
• Removing quotes may allow a broader search: (( modified exact solution algorithms ) or ( modified dorcadmplexity approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified exact solution algorithms") or ("modified dorcadmplexity approximation algorithms"))*.
