Perhaps you should try some spelling variations:
"modified invasive optimization algorithms" » "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified passive optimization algorithms"
"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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive optimization algorithms\") OR (\"machine learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified invasive optimization algorithms ) OR ( machine learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimization algorithms") OR ("machine learning method algorithm"))*.
