Examples of Axiom output that causes problems for the LineBreaker? program:

The Robert Sutor LineBreaker? program is embedded in the LaTeX? handling programs for this web site. It has also been used experimentally in the OldTeXmacs? - Axiom interface program called tm_axiom.

There have been problems reported concerning incorrect formatting that may be due to problems with the LineBreaker? programs. Examples of such problems are collected below.

Experiment 0

The first example below was reported by Andrey G. Grozin as failing when displayed in OldTeXmacs? when using the Sutor line-break algorithm. But typeset and folded correctly by OldTeXmacs? without the line-break algorithm. However it does appear correctly below and it is also correct in the most recent versions of OldTeXmacs? (1.0.4.5 on cygwin and 1.0.4.4 on native windows) when using the newest version of tm_axiom and the version of Axiom at AxiomBinaries?.

Type: Polynomial(Integer)

Experiment 1

This expression is not folded at all by the current version of OldTeXmacs? but it displayed correctly both here and in OldTeXmacs? when using the line-break algorithm.

Type: Fraction(Polynomial(Integer))

Experiment 2

This is the first example in the Jenks and Sutor AXIOM book. It is formatted properly below but in OldTeXmacs? the output is wrong - small instead of large brackets and one of the terms of the numerator not display at all. Without the line-break algorithm OldTeXmacs? displays it correctly but as one long non- folded line.

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.

Experiment 3

This simple variant of the above expression, (-1/3) instead of (1/3), is formatted properly both here and in OldTeXmacs?

Notice that the first term in the paranthesis appears a little odd at first site because the first term itself is "locally folded" at the ${\mathbf \cdot}$ with a vertically centered leading minus sign.
