gm series project
the general-use software
produced as one to handle graphs freely
and for experiments in graph theory
is gm.
this name comes from the initial letters
of "graph manipulator".
we call it just gm since we couldn't find another good name.
however, if we omit the vowels from my name,
we get ngm in fact.
so i feel a kind of destiny with it.
in far future,
when gm evolve into a new big model,
its name will be changed into neo gm,
and we will abbreviate it ngm.
gm standard for macintosh
the first version of gm.
it works on only macintosh,
and sometimes hang up
because i made it without good knowledge on object oriented programing.
gm standard for windows95
the standard form of gm working on windows95.
now the version 1.01 is available.
make contact to negami@edhs.ynu.ac.jp
if you want it.
gm learning
learning system for graph theory,
based on gm standard and for macintosh.
you can try the world of graph theory,
using your mouse.
now, it is open in my homepace,
entitled
"learning graph theory on internet",
but only japanese version is available.
some part depends on browsers
and is needed to be changed.
there are some uncompleted ones.
gm applet
this can be produced
to let the functions of gm standard available on internet.
it is advantage to use it with any browser,
independently of machines.
however,
it cannot access files
wince it works via network.
that is, you cannot save your data you made with it.
gm learning also includes it
in the page entitled
"road to gm applet".
gm for kids
this is gm for children.
for example, the face of bigs, dogs and other animals
represent vertices.
will be represented
i am planning any idea to bring out the sense on discrete mathematics
that children have potentially.
gm geometry
this will be a software to support learning plane geometry.
it is famous that
cabri geometry was born after cabri graph,
which is a software for graph theory.
mimiking this,
i will modify gm to adapt to plane geometry.
i hope this will be a good software made in japan,
corresponding to cabri geometry.
gm topological
since i am an pioneer
of topological graph theory
in japan,
i should improve gm to handle
not only usual graphs, but also graphs on closed surfaces.
there are so many technical difficulties to do it
that it will not appear soon.
what is called gm on torus
will be good enough.
gm 3d
this will be 3d version of gm standard.
that is, it will handle those graphs that are placed in the 3-space.
it might lead us to nice education for stereographical geometry.
gm 4d
beyond 3d,
i want to handle graphs in the 4-dimensional space
and expect it will enable us to see the 4d world.
