Perhaps you should try some spelling variations:
"modified make optimisation algorithms" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make estimation algorithm", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimisation algorithms"
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation 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 make optimisation algorithms") OR ("modified parameters optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified make optimisation algorithms\") OR (\"modified parameters optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified make optimisation algorithms ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimisation algorithms") OR ("modified parameters optimization algorithms"))*.
