stability

tie/leash	maximum gap, 	e.g. 87 	two variables or a variable and a fixed reference value
min		minimum value	e.g. 10 
max		maximum value	e.g. 890
spacer		minimum gap, 	e.g. 15		two variables or a variable and a fixed reference value


physical stops/ties/etc, calcs




game theory resets

spacers
stop iteration and split to large number of items
