Perhaps you should try some spelling variations:
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation algorithm"
"same optimisation algorithmssssssssssss" » "game optimization algorithmssssssssssss", "stage optimization algorithmssssssssssss", "_ optimisation algorithmssssssssssss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("same optimisation algorithmssssssssssss") OR ("parameters optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimisation algorithmssssssssssss\") OR (\"parameters optimization algorithms\"))".
• Removing quotes may allow a broader search: (( same optimisation algorithmssssssssssss ) OR ( parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("same optimisation algorithmssssssssssss") OR ("parameters optimization algorithms"))*.
