Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ estimation algorithm"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimize algorithms", "_ optimise algorithms"
"same optimized algorithm" » "same optimized algorithms", "some optimized algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("same optimized algorithm") OR ((("_ optimizer algorithms") OR ("_ optimization algorithms"))))~.
• Removing quotes may allow a broader search: (( same optimized algorithm ) or ((( _ optimizer algorithms ) or ( _ optimization algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("same optimized algorithm") or ((("_ optimizer algorithms") or ("_ optimization algorithms"))))*.
