Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"most optimizer algorithms" » "most optimized algorithms", "most optimization algorithms"
"post optimized algorithm" » "post optimized algorithms", "cost optimized algorithm"

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: "((((\"post optimized algorithm\") OR (\"most optimizer algorithms\"))) OR (\"_ estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( post optimized algorithm ) OR ( most optimizer algorithms ))) OR ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("post optimized algorithm") OR ("most optimizer algorithms"))) OR ("_ estimation algorithms"))*.
