Initial checkin of Pika from heckimp

* Comment:
* CML is the abbreviation of Coupled-Map Lattice that is a model of
* complex systems, proposed by a physicist[1,2].
*
* Similar models are summaried as follows:
*
* Value Time Space
* Coupled-Map Lattice cont. discrete discrete
Updated with upstream update
2023-10-30 23:55:30 +01:00
* Cellular Automata discrete discrete discrete
Initial checkin of Pika from heckimp
2023-09-26 00:35:21 +02:00
* Differential Eq. cont. cont. cont.
*
* (But this program uses a parameter: hold-rate to avoid very fast changes.
* Thus time is rather continuous than discrete.
* Yes, this change to model changes the output completely.)
*
* References:
* 1. Kunihiko Kaneko, Period-doubling of kind-antikink patterns,
* quasi-periodicity in antiferro-like structures and spatial
* intermittency in coupled map lattices -- Toward a prelude to a
* "field theory of chaos", Prog. Theor. Phys. 72 (1984) 480.
*
* 2. Kunihiko Kaneko ed., Theory and Applications of Coupled Map
* Lattices (Wiley, 1993).
*
* About Parameter File:
* I assume that the possible longest line in CMP parameter file is 1023.
* Please read CML_save_to_file_callback if you want know details of syntax.
*
* Format version 1.0 starts with:
* ; This is a parameter file for CML_explorer
* ; File format version: 1.0
* ;
* Hue
*
* The old format for CML_explorer included in pika-0.99.[89] is:
* ; CML parameter file (version: 1.0)
* ; Hue
*
* (This file format is interpreted as format version 0.99 now.)
*
* Thanks:
* This version contains patches from:
* Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>
* Sean P Cier <scier@andrew.cmu.edu>
* David Mosberger-Tang <davidm@azstarnet.com>
