1. A method for generating a dimensionally tractable set of image layout constraints, said method comprising: applying, performed by a computer, a selected constraint to limit a dimension of a highly dimensional solution space; and identifying, performed by said computer, through random selection one or more unconstrained dimensions of said highly dimensional solution space, which when constrained will further limit said highly dimensional solution space to a dimensionally tractable solution space, wherein tractability of said dimensionally tractable solution space is associated with a capability of a computational resource.
