Perhaps you should try some spelling variations:
"implementing control algorithm" » "implementing context algorithm" (Expand Search), "representing control algorithm" (Expand Search), "complementary control algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("implementing control algorithm") OR ("relevant data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implementing control algorithm\") OR (\"relevant data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( implementing control algorithm ) OR ( relevant data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implementing control algorithm") OR ("relevant data algorithm"))) OR ("data using algorithm"))*.
