Perhaps you should try some spelling variations:
"modified deep convolution algorithms" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified deep convolutional algorithms", "modified delphi convolution algorithms", "modified df convolution algorithms", "modified near convolution algorithms"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation 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 deep convolution algorithms\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified deep convolution algorithms ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified deep convolution algorithms") OR ("modified objective optimization algorithm"))*.
