Perhaps you should try some spelling variations:
"climate modeling algorithm" » "climate making algorithm" (Expand Search), "climate models algorithm" (Expand Search), "climate model algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"image using algorithms" » "image pacing algorithms" (Expand Search), "image nine algorithms" (Expand Search), "image sorting algorithms" (Expand Search), "images using algorithms" (Expand Search), "made using algorithms" (Expand Search), "imaging using algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("climate modeling algorithm") OR ("image using algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"climate modeling algorithm\") OR (\"image using algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( climate modeling algorithm ) OR ( image using algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("climate modeling algorithm") OR ("image using algorithms"))) OR ("element method algorithm"))*.
