tvm::arith::IntConstraintsTransformNode Class Reference

We can have different set of variables to represent the same constraints. For example, the following two systems are equivalent, {a + b = 0 | a >= 0, b >= 0} and {m - n = 0 | m >= 0, n <= 0} This data structure represents the transformation between two equivalent linear systems. In the above example, src : {a + b = 0 | a >= 0, b >= 0} dst : {m - n = 0 | m >= 0, n <= 0} src_to_dst : {a -> m, b -> -n} dst_to_src : {m -> a, n -> -b}. More...

Detailed Description

We can have different set of variables to represent the same constraints. For example, the following two systems are equivalent, {a + b = 0 | a >= 0, b >= 0} and {m - n = 0 | m >= 0, n <= 0} This data structure represents the transformation between two equivalent linear systems. In the above example, src : {a + b = 0 | a >= 0, b >= 0} dst : {m - n = 0 | m >= 0, n <= 0} src_to_dst : {a -> m, b -> -n} dst_to_src : {m -> a, n -> -b}.
