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