Perhaps you should try some spelling variations:
"modified learning convolution algorithmss" » "modified learning convolution algorithms", "modified learning evolution algorithm", "mobile learning convolution algorithmss", "modified caging convolution 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 objective optimisation algorithm") or ("modified learning convolution algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithm") OR ("modified learning convolution algorithmss")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified learning convolution algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified learning convolution algorithmss"))*.
