This question is connected to my previous topic How can I express these constraints in CVX?
The model changed slightly!
The constraints have become too complex for me to put in CVX. The constraints are as follows

x_{t,t''} \ge x_{t,t'} + x_{t',t''}  1\quad \forall t,t',t'' \ni t\neq t' \,\&\, t' \neq t'' \,\&\, t \neq t''.

x_{t,t} + x_{t',t'} + x_{t,t'}\le 2 \quad\forall t < t'.
Any help!
