Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"post modeling algorithm" » "post scheduling algorithm" (Expand Search), "most modeling algorithm" (Expand Search), "cost modeling algorithm" (Expand Search)
"present data algorithm" » "present jaya algorithm" (Expand Search), "present 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: (("present data algorithm") OR ((("image processing algorithm") OR ("post modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithm\") OR (((\"image processing algorithm\") OR (\"post modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( present data algorithm ) OR ((( image processing algorithm ) OR ( post modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present data algorithm") OR ((("image processing algorithm") OR ("post modeling algorithm"))))*.
