Perhaps you should try some spelling variations:
"improvements using algorithms" » "improvements cosine algorithm" (Expand Search), "improvement using algorithms" (Expand Search)
"data making algorithm" » "data cosine algorithm" (Expand Search), "data mining algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements using algorithms\") OR (\"element data algorithm\"))) OR (\"data making algorithm\"))~".
• Removing quotes may allow a broader search: (((( improvements using algorithms ) OR ( element data algorithm ))) OR ( data making algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("improvements using algorithms") OR ("element data algorithm"))) OR ("data making algorithm"))*.
