[r-t] 23-spliced TB major

Fri Apr 30 14:07:55 UTC 2010

I've been thinking a bit more about generating random methods for an arbitrary peal of 23-spliced.

The simplest way to do this seemed to be with excel. In column A, I just entered the different possible changes for row 1. Cells A2:A13 therefore read:

X

34

36

38

56

58

78

3456

3478

3458

5678

345678

To select one of these at random, I then just enter the formula below.

=INDIRECT("A"&RANDBETWEEN(2,13))

Columns B onwards are used for subsequent changes in the lead, and the notation for a lead brought together using the concatenate function.

Of course, the danger here is that methods are trivially false, eg with the same bit of place notation appearing in adjacent changes.  To screen out these, I ran the methods through Richard Smith's method filter, which produced just a list of methods with true 7-lead plain courses.

The first 23 such methods generated were:

I like the complete lack of subjectivity in the method selection in this approach.

All that's needed now is a composition...
