Perhaps you should try some spelling variations:
"solved using algorithms" » "solved pacing algorithms" (Expand Search), "solved nine algorithms" (Expand Search), "solved sorting algorithms" (Expand Search)
"fragment based algorithm" » "agent based algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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 finding algorithm") OR ("solved using algorithms"))) OR ("fragment based algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data finding algorithm\") OR (\"solved using algorithms\"))) OR (\"fragment based algorithm\"))".
• Removing quotes may allow a broader search: (((( data finding algorithm ) OR ( solved using algorithms ))) OR ( fragment based algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data finding algorithm") OR ("solved using algorithms"))) OR ("fragment based algorithm"))*.
