Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified parameter estimation algorithmss" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified allocation optimisation algorithm") OR ("modified parameter estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimisation algorithm\") OR (\"modified parameter estimation algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) OR ( modified parameter estimation algorithmss ))*.
