Perhaps you should try some spelling variations:
"post routing algorithm" » "post cosine algorithm" (Expand Search), "most routing algorithm" (Expand Search), "cost routing algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data scheduling algorithm" » "task scheduling algorithm" (Expand Search), "ahead scheduling algorithm" (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: "((((\"data scheduling algorithm\") OR (\"post routing algorithm\"))) OR (\"element method algorithm\"))~".
• Removing quotes may allow a broader search: (((( data scheduling algorithm ) OR ( post routing algorithm ))) OR ( element method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("data scheduling algorithm") OR ("post routing algorithm"))) OR ("element method algorithm"))*.
