Perhaps you should try some spelling variations:
"modified trace convolution algorithms" » "modified trace evolution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms", "modified male convolution algorithms", "modified orca convolution algorithms"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective estimation algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified trace convolution algorithms") or ("modified objective solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trace convolution algorithms") OR ("modified objective solution algorithm")).
• Removing quotes may allow a broader search: (( modified trace convolution algorithms ) or ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified trace convolution algorithms") or ("modified objective solution algorithm"))*.
