Compare JuMP model constraint statistics between two model directories

Source: R/utils.R
compare_jump_stats.Rd

Reads constraint statistics CSV files from two JuMP model solver directories and compares constraint counts and non-zero counts. Useful for validating model generation changes.

Usage

compare_jump_stats(
  model_dir1,
  model_dir2,
  save_comparison = TRUE,
  verbose = TRUE
)

Arguments

model_dir1

Path to first model's solver/jump directory (e.g., "tmp/model_v1/solvers/jump")

model_dir2

Path to second model's solver/jump directory (e.g., "tmp/model_v2/solvers/jump")

save_comparison

Logical; if TRUE, saves merged comparison to CSV in model_dir1's parent directory

verbose

Logical; if TRUE, prints detailed comparison results

Value

A list with components:

merged

Data frame with merged statistics from both models

constraint_mismatches

Data frame of equations with different constraint counts

nnz_differences

Data frame of equations with different non-zero counts

summary

Named list with total counts and match status

Examples

if (FALSE) { # \dontrun{
# Compare two JuMP model versions
comp <- compare_jump_stats(
  "tmp/model_v1/solvers/jump",
  "tmp/model_v2/solvers/jump",
  verbose = TRUE
)

# Check if models match
if (comp$summary$all_match) {
  message("Models are identical!")
}
} # }
