## Stochastic optimization

The localization problem that I am trying to solve is to figure out the position of passive RFID tags in a box. Essentially I measure the backscattered signals from the RFID tags and try to figure out their relative position. The problem is formulated as a statistical maximum a-posteriori (MAP) estimator where the unknown parameters are the radial separation between the tags and they will be estimated from the backscattered signal strength measurements. The objective functio
