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