Perhaps you should try some spelling variations:
"post making algorithm" » "post learning algorithm" (Expand Search), "post finding algorithm" (Expand Search), "post means algorithm" (Expand Search), "poster making algorithm" (Expand Search), "post aging algorithm" (Expand Search), "post marketing algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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 modeling algorithm") OR ("post making algorithm"))) OR ("element mesh algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"post making algorithm\"))) OR (\"element mesh algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( post making algorithm ))) OR ( element mesh algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("post making algorithm"))) OR ("element mesh algorithm"))*.
