Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified adaptive convolution algorithmss" » "modified adaptive convolution algorithms", "modified adaptive evolution algorithm", "modified adaptive construction algorithmss", "modified adaptive ventilation algorithmss", "modified passive convolution algorithmss"

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

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