Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified time evolution algorithm" » "modified time solution algorithm", "modified time evolutionary algorithm", "modified time convolution algorithms", "modified bi1 evolution algorithm", "modified male evolution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time evolution algorithm") OR ("modified parameters optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified time evolution algorithm ) or ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time evolution algorithm") or ("modified parameters optimisation algorithm"))*.
