Perhaps you should try some spelling variations:
"modified df convolutional algorithmss" » "modified df convolution algorithms", "modified d convolutional algorithmss", "modified deep convolutional algorithmss", "modified _ convolutional algorithmss", "modified adam convolutional algorithmss", "modified bi1 convolutional algorithmss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 df convolutional algorithmss") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df convolutional algorithmss") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified df convolutional algorithmss ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df convolutional algorithmss") or ("modified objective optimisation algorithm"))*.
