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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter optimization algorithm") or ("modified pose optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithm") OR ("modified pose optimisation algorithms")).
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( modified pose optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") or ("modified pose optimisation algorithms"))*.
