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