Perhaps you should try some spelling variations:
"image 3_targeting algorithm" » "image 1_targeting algorithm" (Expand Search), "image 2_targeting algorithm" (Expand Search)
"solved using algorithm" » "solved using algorithms" (Expand Search), "solved routing algorithm" (Expand Search), "solved fusion algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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 3_targeting algorithm") OR ("solved using algorithm"))) OR ("element data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 3_targeting algorithm\") OR (\"solved using algorithm\"))) OR (\"element data algorithms\"))".
• Removing quotes may allow a broader search: (((( image 3_targeting algorithm ) OR ( solved using algorithm ))) OR ( element data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("image 3_targeting algorithm") OR ("solved using algorithm"))) OR ("element data algorithms"))*.
