I'm asking targen "enlarge the target" function which means to add new patches
to existing data optimally. For example, I have 500 patches freshly red patches
data. I'm restricted in printing a high number of patches but discovered that
500 current patches isn't enough to build a quality profile. I can print 500
patches more. But if new 500-patches target will be generated without taking
the previous target in account, many of they patches will likely be placed in
the proximity to previous target patches. The target wouldn't be optimal
because of patch doubling (not exact doubling but in small area). So the
accounting of previous target needed. The patches from previous target will be
"fixed" while new target generation. I hope the current optimization algorithm
permits this.
