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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimization algorithm") or ("_ estimation algorithms"))) or ("post optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimization algorithm") OR ("_ estimation algorithms"))) OR ("post optimizer algorithms")).
• Removing quotes may allow a broader search: (((( _ optimization algorithm ) or ( _ estimation algorithms ))) or ( post optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithm") or ("_ estimation algorithms"))) or ("post optimizer algorithms"))*.
