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 remaining tutorial that runs HiGHS — 12
m.solve(...)calls across 4 notebooks:create-a-model.ipynb(1)create-a-model-with-coordinates.ipynb(1)manipulating-models.ipynb(9)transport-tutorial.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) merged first and already added
output_flag=Falsetopiecewise-linear-constraints.ipynbandpiecewise-inequality-bounds.ipynbas part of its broader rewrite. On merging master into this branch, the conflict on those two notebooks was resolved by taking master's version, so they are no longer part of this PR's diff.Test plan
