HiGHS prints a banner + progress lines to the Python REPL on every m.solve() call by default. In a tutorial that calls solve many times, this drowns the actual lesson in solver chatter. Pass output_flag=False (a HiGHS solver option forwarded via **solver_options) to suppress it. Touches the four notebooks where solver_name="highs" is the only solver invoked: - create-a-model.ipynb - create-a-model-with-coordinates.ipynb - manipulating-models.ipynb (9 solves) - transport-tutorial.ipynb Left alone: - infeasible-model.ipynb (uses Gurobi, kwarg is OutputFlag there; also showing solver feedback may be pedagogically relevant for infeasibility detection). - solve-on-remote.ipynb / solve-on-oetc.ipynb (remote handler manages its own logging). - piecewise-*.ipynb (already addressed in #677).

Extends the log-silencing scope to the two piecewise tutorials, which together call m.solve() nine times. Same transformation as the other notebooks — output_flag=False as a HiGHS-specific kwarg forwarded via **solver_options. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
HiGHS prints a banner + progress lines to the Python REPL on every
m.solve()call by default. In a tutorial that calls solve many times (e.g.manipulating-models.ipynbhas 9), this drowns the actual lesson in solver chatter. Passingoutput_flag=False(a HiGHS solver option forwarded via**solver_options) suppresses it.Touches every tutorial that runs HiGHS — 21
m.solve(...)calls across 6 notebooks:create-a-model.ipynb(1)create-a-model-with-coordinates.ipynb(1)manipulating-models.ipynb(9)transport-tutorial.ipynb(1)piecewise-linear-constraints.ipynb(8)piecewise-inequality-bounds.ipynb(1)Left alone:
infeasible-model.ipynb— uses Gurobi (kwarg isOutputFlagthere); also showing solver feedback may be pedagogically relevant for infeasibility detection.solve-on-remote.ipynb/solve-on-oetc.ipynb— remote handler manages its own logging.Note on overlap with #677
#677 (piecewise precision pass) also adds
output_flag=Falseto the piecewise tutorials as part of its broader cleanup. Whichever PR merges first will resolve the duplicate diff trivially.Test plan
