Perhaps you should try some spelling variations:
"image 2_mapping algorithm" » "image making algorithm" (Expand Search), "image scraping algorithm" (Expand Search), "image sampling algorithm" (Expand Search), "image 1_mapping algorithm" (Expand Search), "image 3_mapping algorithm" (Expand Search), "image 2_machine algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 modeling algorithm") OR ("image 2_mapping algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"image 2_mapping algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( image 2_mapping algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("image 2_mapping algorithm"))) OR ("relevant data algorithm"))*.
