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