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

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("post optimized algorithm") OR ("post optimizer algorithms"))) OR ("_ estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post optimized algorithm\") OR (\"post optimizer algorithms\"))) or (\"_ estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( post optimized algorithm ) OR ( post optimizer algorithms ))) or ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("post optimized algorithm") OR ("post optimizer algorithms"))) or ("_ estimation algorithms"))*.
