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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimizer algorithms\") OR (((\"_ optimization algorithm\") OR (\"_ estimation algorithms\"))))~".
• Removing quotes may allow a broader search: (( same optimizer algorithms ) OR ((( _ optimization algorithm ) OR ( _ estimation algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("same optimizer algorithms") OR ((("_ optimization algorithm") OR ("_ estimation algorithms"))))*.
