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