Perhaps you should try some spelling variations:
"Ant scheduling optimization algorithm" » "Ant cooling optimization algorithm" (Expand Search)
"ant colony optimisation algorithm" » "ant colony optimization algorithm" (Expand Search)
ant scheduling » task scheduling (Expand Search), _ scheduling (Expand Search)

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: "((\"Ant scheduling optimization algorithm\") OR (\"ant colony optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( Ant scheduling optimization algorithm ) OR ( ant colony optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("Ant scheduling optimization algorithm") OR ("ant colony optimisation algorithm"))*.
