Perhaps you should try some spelling variations:
"level coding algorithms" » "level sorting algorithms" (Expand Search), "level finding algorithms" (Expand Search), "level cosine algorithm" (Expand Search), "level according algorithms" (Expand Search), "level modeling algorithms" (Expand Search), "level using algorithms" (Expand Search)
"effects model algorithm" » "effects novel algorithm" (Expand Search), "effects modbo algorithm" (Expand Search), "effects modeling algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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: (("movement data algorithm") OR ((("level coding algorithms") OR ("effects model algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement data algorithm\") OR (((\"level coding algorithms\") OR (\"effects model algorithm\"))))".
• Removing quotes may allow a broader search: (( movement data algorithm ) OR ((( level coding algorithms ) OR ( effects model algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement data algorithm") OR ((("level coding algorithms") OR ("effects model algorithm"))))*.
