Perhaps you should try some spelling variations:
"post modeling algorithm" » "post scheduling algorithm" (Expand Search), "most modeling algorithm" (Expand Search), "cost modeling algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh algorithm" (Expand Search)
"data relating algorithm" » "data regulating algorithm" (Expand Search), "data relations algorithm" (Expand Search), "data relative 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: (((("data relating algorithm") OR ("post modeling algorithm"))) OR ("element mesh algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data relating algorithm\") OR (\"post modeling algorithm\"))) OR (\"element mesh algorithm\"))".
• Removing quotes may allow a broader search: (((( data relating algorithm ) OR ( post modeling algorithm ))) OR ( element mesh algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data relating algorithm") OR ("post modeling algorithm"))) OR ("element mesh algorithm"))*.
