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