Perhaps you should try some spelling variations:
"pose optimization algorithms" » "pose optimisation algorithm", "pose estimation algorithms", "pose estimation algorithm", "qoe optimization algorithms", "game optimization algorithms", "response optimization algorithms"
"_ simulation algorithm" » "_ estimation algorithm", "_ optimisation algorithm", "_ estimation algorithms"
"nacl solution algorithm" » "nacl evolution algorithm", "nacl convolution algorithms", "nacl evolutionary algorithm", "exact solution algorithm", "nodal 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: (((("_ simulation algorithm") or ("nacl solution algorithm"))) or ("pose optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ simulation algorithm") OR ("nacl solution algorithm"))) OR ("pose optimization algorithms")).
• Removing quotes may allow a broader search: (((( _ simulation algorithm ) or ( nacl solution algorithm ))) or ( pose optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ simulation algorithm") or ("nacl solution algorithm"))) or ("pose optimization algorithms"))*.
