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 adaptive solution algorithm" » "modified adaptive evolution algorithm", "modified adaptive convolution algorithms", "modified adaptive evolutionary algorithm", "modified passive solution algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified static optimisation algorithm") or ("modified adaptive solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithm") OR ("modified adaptive solution algorithm")).
• Removing quotes may allow a broader search: (( modified static optimisation algorithm ) or ( modified adaptive solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimisation algorithm") or ("modified adaptive solution algorithm"))*.
