Perhaps you should try some spelling variations:
"write optimization algorithmssss" » "write optimisation algorithm", "write optimisation algorithmsss", "write estimation algorithmssss", "write estimation algorithmsss", "game optimization algorithmssss", "qoe optimization algorithmssss", "stage optimization algorithmssss"
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation 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: "((\"write optimization algorithmssss\") OR (\"parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( write optimization algorithmssss ) OR ( parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("write optimization algorithmssss") OR ("parameters optimization algorithms"))*.
