Perhaps you should try some spelling variations:
"modified adaptive optimisation algorithm" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified passive optimisation algorithm"
"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 adaptive optimisation algorithm") OR ("modified invasive evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive optimisation algorithm ) or ( modified invasive evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimisation algorithm") or ("modified invasive evolution algorithm"))*.
