#X text 516 57 random search for an attractor \, variables use defaults
;
#X text 17 403 The search method implemented performs the following:
;
#X text 41 418 1 Set the params randomly based on allowed ranges;
#X text 41 432 2 Calculate the Lyapunov Exponent;
#X text 41 447 3 If the Lyapunov Exponent is within allowed range \,
return the attractor set;
#X text 19 39 Searching for an attractor set can be as simple as sending
a 'search' message to a fractal. This will search the fractals allowable
parameter limits for an attractor set.;

;
#X text 17 323 The Lyapunov Exponent for the attractor set will indicates
one of three states \, (1) Convergence [a negative value] \, (2) Stability
[0 \, of values close to 0] \, and (3) Chaos [a positive value]. Each
class will have different ranges of Lyapunov Exponent.;
#X text 39 196 arg[2] = Classification String ****;
#X text 16 513 **** - The classification method was adopted from Julian
Sprott's method of classification. While it is an arbitrary system
\, and does not "uniquely" identify an attractor set \, it is used
to show a relationship with other attractor sets with similar values.

number of failures until a solution is found over the total number
of times the search algorithm will be executed before giving up. This
limit is set via the 'lyapunov' message. This number will also be influenced
by the 'low' and 'high' ranges set.;

outlets. These three outlets encapsulate that three pieces of data
of interest. The first of the 'search' outlets holds a list of the
results. This includes:;
#X text 39 170 arg[0] = 'show' \, 'search' \, or 'invalid';
#X text 18 269 Most likely \, you won't see any failures ('invalid')
\, unless you mess with the 'constrain' or 'lyapunov' messages. 'show'
is returned when you use the 'show' message.;
