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.

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