Perhaps you should try some spelling variations:
"spatial scheduling algorithm" » "optimal scheduling algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"data code algorithm" » "data cosine algorithm" (Expand Search), "data rd algorithm" (Expand Search), "data colony algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("data code algorithm") OR ("spatial scheduling algorithm"))) OR ("elements method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data code algorithm\") OR (\"spatial scheduling algorithm\"))) OR (\"elements method algorithm\"))*".
• Removing quotes may allow a broader search: (((( data code algorithm ) OR ( spatial scheduling algorithm ))) OR ( elements method algorithm ))*.
