Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimization algorithms", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified pose optimisation algorithm" » "modified pose optimization algorithms", "modified pose estimation algorithm", "modified pose estimation algorithms", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified male optimisation algorithm", "modified passive optimisation algorithm"

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

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