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