Perhaps you should try some spelling variations:
"modified based convolution algorithms" » "modified based evolution algorithm", "modified based solution algorithm", "modified dilated convolution algorithms", "modified based continuation algorithms", "modified male convolution algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithm\") OR (\"modified based convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective estimation algorithm ) OR ( modified based convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithm") OR ("modified based convolution algorithms"))*.
