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