Perhaps you should try some spelling variations:
"ant scheduling optimization algorithm" » "ant cooling optimization algorithm" (Expand Search), "task scheduling optimization algorithm" (Expand Search), "_ scheduling optimization algorithm" (Expand Search), "ant scheduling optimization algoritmo" (Expand Search)
"a base optimization algorithm" » "a based optimization algorithm" (Expand Search), "a stage optimization algorithm" (Expand Search), "a path optimization algorithm" (Expand Search), "a base optimization algoritmo" (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: "((\"a base optimization algorithm\") OR (\"ant scheduling optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( a base optimization algorithm ) OR ( ant scheduling optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("a base optimization algorithm") OR ("ant scheduling optimization algorithm"))*.
