Perhaps you should try some spelling variations:
"image 1_decoding algorithm" » "image modeling algorithm" (Expand Search), "image 1_developing algorithm" (Expand Search), "table 1_decoding algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data 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: (((("image 1_decoding algorithm") OR ("data using algorithms"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_decoding algorithm\") OR (\"data using algorithms\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_decoding algorithm ) OR ( data using algorithms ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_decoding algorithm") OR ("data using algorithms"))) OR ("element update algorithm"))*.
