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