I've changed to non-TeX inline math notation. But if you code this in TeX, please note:

WRONG: w_{min}

BETTER, but still problematic: w_\mbox{min}

BETTER STILL, but not best: w_\text{min}

RIGHT: w_\min

Here's how they come out:

w_{min}\,

w_{\mbox{min}}\,

w_{\text{min}}\,

w_{\min }\,

\min is a built-in math operator name in TeX. Michael Hardy (talk) 16:26, 24 August 2008 (UTC)[reply]

There is a problem with the definition in combination with the claim concerning the relation to the minimum distance of a linear code. The minimum weight of a linear code (as defined now) is 0, since the all-zero codeword is in the code and has weight 0. Therefore, we want to define the minimum weight of a linear code as the smallest nonzero weight of a codeword. So it makes sence to keep that definition for all codes...Hdlh (talk) 13:13, 25 September 2013 (UTC)[reply]
