### Ising NiO model energy

I am simulating Ising model for NiO. I have simulated for 2d,3d,triangular lattices, and have tried to do the same with NiO model. There are papers which say that the ground state energy is around -...

### Best place to start learning Stereophotogrammetry

Firstly I would like to achieve a final goal as can be found in the links below: Link 1 Link 2 Now I started doing a little bit of research and found that Stereophotogrammetry is the field I should ...
Convert the following model into an LP model. Note that you're not being asked to convert this to standard form. $$\min z = \max (x_1, x_2, x_3, 2000)$$ s.t. $$-2x_1 + x_2 + x_3 \geq -4$$ 3x_1 - ...
