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