Statistics

Reference

Find the reference for the statistics module here.

ModelStatistics allows access to the statistics of a gurobipy.Model. It is a convenience function that will collect a simple set of statistics.

Consider the same script shown in the model section, which solves a simple knapsack problem. You may use the ModelStatistics to obtain the statistics of the model. This convenience functionality is provided out of the box, but we recommend that you customize how the model is interpreted to extract statistics.

import json

import nextmv_gurobipy as ngp

# Model code here.

statistics = ngp.ModelStatistics(model, start_time)
print(json.dumps(statistics.to_dict(), indent=2))

Run the script:

python main.py
{
  "run": {
    "duration": 0.004244089126586914
  },
  "result": {
    "duration": 0.00031304359436035156,
    "value": 444.0,
    "custom": {
      "status": "OPTIMAL",
      "variables": 11,
      "constraints": 1
    }
  },
  "series_data": {},
  "schema": "v1"
}
