comment Largest possible 2D combination not containing 2 common rectangles
@GerryMyerson : I don't know how better to describe it, in case of 1D, consider a sequence, it is longest common sequence that can be found in more than 1 place in the sequence .

revised Why?$\int_0^1\int_{u(t)}^{u(t)+w(t)} f(t,v(t)) dv dt = \int_0^1 f(t,u(t)+\theta w(t))w(t) dt; ~~\theta\in[0,1] $
