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"
"mobile learning method algorithm" » "mobile learning mom algorithm", "machine learning method algorithm", "mobile learning methods algorithm", "mobile graining methods algorithm", "mobile 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 optimisation algorithm\") OR (\"mobile learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified invasive optimisation algorithm ) OR ( mobile learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimisation algorithm") OR ("mobile learning method algorithm"))*.
