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