Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm"
"mode control method algorithm" » "mode control mom algorithm", "mode control methods algorithm", "case control method algorithm", "mimo control method 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 parameters optimization algorithm") OR ("mode control method algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( mode control method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("mode control method algorithm"))*.
