Perhaps you should try some spelling variations:
"modified invasive optimization algorithmss" » "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified passive optimization algorithmss"
"modified adaptive quantization algorithms" » "modified adaptive estimation algorithms", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithms", "modified passive quantization algorithms"

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 invasive optimization algorithmss") OR ("modified adaptive quantization algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive optimization algorithmss ) or ( modified adaptive quantization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimization algorithmss") or ("modified adaptive quantization algorithms"))*.
