Perhaps you should try some spelling variations:
"case modeling algorithm" » "case scheduling algorithm" (Expand Search), "based modeling algorithm" (Expand Search)
"pooled using algorithms" » "pooled cosine algorithm" (Expand Search), "problem using algorithms" (Expand Search), "tool using algorithms" (Expand Search), "tools using algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method 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: (((("case modeling algorithm") OR ("pooled using algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"case modeling algorithm\") OR (\"pooled using algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( case modeling algorithm ) OR ( pooled using algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("case modeling algorithm") OR ("pooled using algorithms"))) OR ("element method algorithm"))*.
