Directly compares variable solution files without loading full model. Handles different data formats (e.g., CSV from GMPL, Arrow from JuMP).
Usage
compare_solution(
path1,
path2,
solver1 = NULL,
solver2 = NULL,
variables = NULL,
tol = 1e-05,
keep = c("differences", "all", "matches"),
allowAll = TRUE,
verbose = TRUE
)Arguments
- path1
Path to first solver output directory (reference/expected)
- path2
Path to second solver output directory (to compare)
- solver1
Solver name for path1 if it's a model root (e.g., "gmpl", "jump"). NULL for direct solution paths.
- solver2
Solver name for path2 if it's a model root (e.g., "gmpl", "jump"). NULL for direct solution paths.
- variables
Character vector of variable names to compare. If NULL, compares all common variables.
- tol
Numeric tolerance for comparing values (default 1e-5)
- keep
What to return: "all", "differences", "matches" (default "differences")
- allowAll
Passed to compare::compare() - allows all transformations (default TRUE)
- verbose
Print comparison details (default TRUE)
