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