Perhaps you should try some spelling variations:
"modified make optimisation algorithms" » "modified make optimisation algorithm", "modified make optimization algorithms", "modified make estimation algorithms", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimisation algorithms"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified 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: "((\"modified make optimisation algorithms\") OR (\"modified parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified make optimisation algorithms ) OR ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make optimisation algorithms") OR ("modified parameters optimization algorithm"))*.
