Perhaps you should try some spelling variations:
"modified caging convolution algorithm" » "modified caging convolution algorithms", "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm"
"modified location estimation algorithms" » "modified location estimation algorithm", "modified location optimization algorithms", "modified location optimisation algorithm", "modified motion estimation algorithms", "modified carbon estimation 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 location estimation algorithms") OR ("modified caging convolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified location estimation algorithms\") OR (\"modified caging convolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified location estimation algorithms ) OR ( modified caging convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified location estimation algorithms") OR ("modified caging convolution algorithm"))*.
