Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified global solution algorithm" » "modified global evolution algorithm", "modified global convolution algorithms", "modified global evolutionary algorithm", "modified global solutions algorithm", "modified nodal solution 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 global solution algorithm") OR ("modified parameter optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified global solution algorithm ) or ( modified parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified global solution algorithm") or ("modified parameter optimization algorithm"))*.
