Perhaps you should try some spelling variations:
"modified orcadmplexity approximation algorithms" » "modified complexity approximation algorithms", "modified dorcadmplexity approximation algorithms", "modified orcaddmplexity approximation algorithms", "modified ohcadmplexity approximation algorithms"
"modified orca convolution algorithms" » "modified orca evolution algorithm", "modified orca solution algorithm", "modified dorca convolution algorithms", "modified orcad convolution algorithms", "modified ohca convolution 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 orca convolution algorithms") or ("modified orcadmplexity approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified orca convolution algorithms") OR ("modified orcadmplexity approximation algorithms"))*.
• Removing quotes may allow a broader search: (( modified orca convolution algorithms ) or ( modified orcadmplexity approximation algorithms ))*.
