Perhaps you should try some spelling variations:
"age modeling algorithm" » "age scheduling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "_ modeling algorithm" (Expand Search)
"image 1_using algorithm" » "image cosine algorithm" (Expand Search)
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer 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_using algorithm") OR ("age modeling algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"age modeling algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( age modeling algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("age modeling algorithm"))) OR ("relevant data algorithm"))*.
