Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified total approximation algorithms" » "modified one approximation algorithms", "modified time approximation algorithms", "modified rough approximations algorithms", "modified thermal approximation algorithms", "modified ti6al4v approximation 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 total approximation algorithms") OR ("modified objective convolution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified total approximation algorithms\") OR (\"modified objective convolution algorithms\"))".
• Removing quotes may allow a broader search: (( modified total approximation algorithms ) OR ( modified objective convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified total approximation algorithms") OR ("modified objective convolution algorithms"))*.
