Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"_ optimized algorithms" » "_ optimizer algorithms", "_ optimization algorithms", "_ optimizer algorithmss"
"post optimized algorithm" » "post optimizer algorithms", "most optimized algorithm", "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: "((((\"_ estimation algorithms\") OR (\"_ optimized algorithms\"))) OR (\"post optimized algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) OR ( _ optimized algorithms ))) OR ( post optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") OR ("_ optimized algorithms"))) OR ("post optimized algorithm"))*.
