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