A step of the miprgr_native implementation. No other function in the package calls it.
See the file header for the source the module follows.
Usage
miprgr_round_relaxation(x, A, b, integer_vars)
Arguments
- x
Coerced to numeric by the body, with as.numeric.
- A
A matrix; indexed by row and column.
- b
A vector; indexed elementwise.
- integer_vars
See Usage.
Value
A list with x, feasible, violations, note.
Examples
A <- matrix(c(1, 1, 1, -1), 2, byrow = TRUE)
miprgr_round_relaxation(c(1.4, 2.6), A, b = c(4, 1), integer_vars = c(1, 2))
#> $x
