Perhaps you should try some spelling variations:
"topology optimization algorithm" » "topology optimization algorithms", "topology optimisation algorithm", "topology estimation algorithm"
"a simulation algorithm" » "a estimation algorithm", "a optimisation algorithm", "a estimation algorithms", "_ simulation algorithm"
"a solution algorithm" » "a evolution algorithm", "a convolution algorithms", "a evolutionary algorithm", "_ solution algorithm", "_ solutions algorithm", "nacl 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: (((("a simulation algorithm") OR ("a solution algorithm"))) or ("topology optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a simulation algorithm") OR ("a solution algorithm"))) OR ("topology optimization algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a simulation algorithm\") OR (\"a solution algorithm\"))) or (\"topology optimization algorithm\"))".
• Removing quotes may allow a broader search: (((( a simulation algorithm ) OR ( a solution algorithm ))) or ( topology optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("a simulation algorithm") OR ("a solution algorithm"))) or ("topology optimization algorithm"))*.
