Perhaps you should try some spelling variations:
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation algorithms"
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

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 evolution algorithm") OR ("modified adam estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified adam estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithm") or ("modified adam estimation algorithms"))*.
