Perhaps you should try some spelling variations:
"effects sorting algorithms" » "effects learning algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"tested using algorithms" » "tested cosine algorithm" (Expand Search), "system using algorithms" (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: (("element method algorithm") OR ((("tested using algorithms") OR ("effects sorting algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"tested using algorithms\") OR (\"effects sorting algorithms\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( tested using algorithms ) OR ( effects sorting algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("tested using algorithms") OR ("effects sorting algorithms"))))*.
