Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"_ optimized algorithms" » "_ optimizer algorithms", "_ optimization algorithms", "_ optimizer algorithmss"
"doan optimized algorithm" » "doan optimizer algorithms", "doanh optimized algorithm", "dan optimized algorithm", "toan optimized algorithm"

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 optimized algorithm") or ("_ optimized algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("doan optimized algorithm") OR ("_ optimized algorithms"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( doan optimized algorithm ) or ( _ optimized algorithms ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("doan optimized algorithm") or ("_ optimized algorithms"))) or ("_ optimisation algorithm"))*.
