Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"doan optimizer algorithms" » "doan optimized algorithm", "doan optimization algorithms", "doanh optimizer algorithms", "dan optimizer algorithms", "toan optimizer algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization 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: (((("doan optimizer algorithms") or ("_ optimized algorithms"))) or ("_ optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("doan optimizer algorithms") OR ("_ optimized algorithms"))) OR ("_ optimization algorithm")).
• Removing quotes may allow a broader search: (((( doan optimizer algorithms ) or ( _ optimized algorithms ))) or ( _ optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("doan optimizer algorithms") or ("_ optimized algorithms"))) or ("_ optimization algorithm"))*.
