Talk:Wang and Landau algorithm

code
The presented code is not correct. It only considers the proposal functions such that

$$g(\boldsymbol{r}\rightarrow\boldsymbol{r}') = g(\boldsymbol{r}\rightarrow\boldsymbol{r}')$$

which is not necessarily true. I don't know D language so I will not change it, but someone should.Jorgecarleitao (talk) 08:17, 29 October 2012 (UTC)
 * it is stated that the code only is for your case.--129.69.120.39 (talk) 11:58, 2 April 2015 (UTC)

Error in the presented Algorithm?
Hi the fraction $$\frac{g(\boldsymbol{r}'\rightarrow \boldsymbol{r})}{g(\boldsymbol{r}\rightarrow \boldsymbol{r}')} $$ in
 * $$A(\boldsymbol{r}\rightarrow \boldsymbol{r}') = \min\left(1,e^{S - S'}\frac{g(\boldsymbol{r}'\rightarrow \boldsymbol{r})}{g(\boldsymbol{r}\rightarrow \boldsymbol{r}')}\right)$$

does not occur in the original Wang-Landau algorithm. Where does it come from, is it correct? --129.69.120.39 (talk) 11:56, 2 April 2015 (UTC)

 * the original algorithm assumed a symmetric proposal distribution. see e.g. Metropolis–Hastings_algorithm Biggerj1 (talk) 13:25, 11 January 2016 (UTC) ✅
