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

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: "((((\"optimization algorithms\") OR (\"optimization algorithmss\"))) OR (\"optimizer algorithms\"))~".
• Removing quotes may allow a broader search: (((( optimization algorithms ) OR ( optimization algorithmss ))) OR ( optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("optimization algorithms") OR ("optimization algorithmss"))) OR ("optimizer algorithms"))*.
