Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"don optimizer algorithms" » "don optimized algorithms", "don optimized algorithm", "don optimization algorithms", "doan optimizer algorithms"
"dong optimizer algorithms" » "dong optimized algorithms", "dong optimized algorithm", "dong optimization algorithms", "doang optimizer algorithms", "cong optimizer algorithms", "dung 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: (((("don optimizer algorithms") OR ("dong optimizer algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("don optimizer algorithms") OR ("dong optimizer algorithms"))) OR ("_ optimisation algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"don optimizer algorithms\") OR (\"dong optimizer algorithms\"))) or (\"_ optimisation algorithm\"))".
• Removing quotes may allow a broader search: (((( don optimizer algorithms ) OR ( dong optimizer algorithms ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("don optimizer algorithms") OR ("dong optimizer algorithms"))) or ("_ optimisation algorithm"))*.
