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