| Jan 31, 2012 at 22:47 | comment | added | SCL | IF $\theta$ in the system above is bounded (e.g. between 0 and $2\pi$) then we can substitute $cos(\theta)$ with $w$ and $\sin(\theta)$ with $z$ and add an additional constraint $z^2 + w^2 = 0$. In this way we can solve the system with known methods for polynomial systems solving (e.g. cylindrical algebraic decomposition). | |

| Jan 27, 2012 at 18:02 | comment | added | zeb | This is at least as hard as 0-1 integer programming - if you set cos(x) = 0, then (1+sin(x))/2 is either 0 or 1... | |
