Talk:Quadratic unconstrained binary optimization

The claim about quantum computing is problematic. The paper by McGeoch was a comparison between optimized hardware and unoptimized software, and further examination has demonstrated no advantage for existing quantum hardware (http://www.archduke.org/stuff/d-wave-comment-on-comparison-with-classical-computers/). If there is a theoretical reason why QUBO would be well-suited to quantum solving, then the article should reference that. 71.186.212.34 (talk) 16:31, 2 July 2013 (UTC)[reply]

Leaving doubts aside, the page does not explain the problem being solved. The formula without annotations is useless. PetrGlad (talk) 09:16, 12 January 2017 (UTC)[reply]

From what domain are $Q_{ij}$ and $X_{i}$ ? HenningThielemann (talk) 21:51, 31 March 2016 (UTC)[reply]

To answer the question above: surely $Q_{ij}$ are real and $X_{i}$ are binary. What bothers me is that the article misses the $sum_{j=1}^{n}a_{i}x_{i}$ which is shown in both the link of Wang and Kleinberg and the q-wave documentation Alexander Mitsos (talk) 21:51, 31 March 2016 (UTC)[reply]
