Table 1:

Weight assignment categories for the organs at risk. The function rand(lb, ub) represents a uniform random number between a lower bound, lb, and an upper bound, ub. In the high, medium, low, extra low, and controlled weights category, the PTV had a 0.05 probability of being assigned rand(0,1) instead of 1.

Category		Description
Single organ spare	Bladder	wbladder = rand(0,1) wOAR\bladder = rand(0,0.1)
	Rectum	wrectum = rand(0,1) wOAR\rectum = rand(0,0.1)
	Lt Fem Head	wlt femhead = rand(0,1) wOAR\lt femhead = rand(0,0.1)
	Rt Fem Head	wrt femhead = rand(0,1) wOAR\rt femhead = rand(0,0.1)
	Shell	wshell = rand(0,1) wOAR\shell = rand(0,0.1)
	Skin	wskin = rand(0,1) wOAR\skin = rand(0,0.1)
High weights		ws = rand(0,1) ∀s ∈ OAR
Medium weights		ws = rand(0,0.5) ∀s ∈ OAR
Low weights		ws = rand(0,0.1) ∀s ∈ OAR
Extra low weights		ws = rand(0,0.05) ∀s ∈ OAR
Controlled weights		wbladder = rand(0,0.2) wrectum = rand(0,0.2) wlt femhead = rand(0,0.1) wrt femhead = rand(0,0.1) wshell = rand(0,0.1) wskin = rand(0,0.3)
