Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"solved using algorithm" » "solved using algorithms" (Expand Search), "solved routing algorithm" (Expand Search), "solved fusion algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (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: "((((\"data modelling algorithm\") OR (\"solved using algorithm\"))) OR (\"element tree algorithms\"))~".
• Removing quotes may allow a broader search: (((( data modelling algorithm ) OR ( solved using algorithm ))) OR ( element tree algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("data modelling algorithm") OR ("solved using algorithm"))) OR ("element tree algorithms"))*.
