Perhaps you should try some spelling variations:
"modified caging optimisation algorithm" » "modified caging optimization algorithms", "modified caging estimation algorithm", "modified caging estimation algorithms", "modified staffing optimization algorithm"
"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"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified deep convolution algorithms") OR ("modified caging optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified deep convolution algorithms\") OR (\"modified caging optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified deep convolution algorithms ) OR ( modified caging optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified deep convolution algorithms") OR ("modified caging optimisation algorithm"))*.
