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