Perhaps you should try some spelling variations:
"parameters optimisation algorithmssssss" » "parameters optimization algorithms", "parameter optimization algorithmssssss", "parameter estimation algorithmssssss", "parameters optimization algorithmsssssss", "parameters estimation algorithmssssss", "parameters estimation algorithmsssssss"
"static optimisation algorithm" » "static optimization algorithms", "static estimation algorithm", "static estimation algorithms", "static optimization algorithm", "stage optimization algorithm", "stochastic optimization 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: (("static optimisation algorithm") or ("parameters optimisation algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("static optimisation algorithm") OR ("parameters optimisation algorithmssssss")).
• Removing quotes may allow a broader search: (( static optimisation algorithm ) or ( parameters optimisation algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("static optimisation algorithm") or ("parameters optimisation algorithmssssss"))*.
