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

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

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