I solved what I yesterday did not understand:
ts'#: i.50000'
0.001647 1311360
datatype i.50000
integer
(i.50000)-:0.5-~0.5+i.50000
1
datatype 0.5-~0.5+i.50000
floating
ts'#: 0.5-~0.5+i.50000'
0.9603186 11864064
So my verb should be made integer:
ncb=: [:|.@; [:(+&.><@;\.)/ [ */&(2<[EMAIL PROTECTED]|[EMAIL
PROTECTED]) >:@-~
(#: nct^:(i.5!28) 31)-: #:5 ncb 28
1
[score=: 5&ts&> '#: nc^:(i.5!28) 31' ;'#: nct^:(i.5!28) 31';'#: 5 ncb 28'
1.7895653 12984256
0.63956285 12984256
0.0072934627 4719552
rnkng=:',0.2,0.2,0.2'(8!:1) ([:(,~/:@/:@{.) [:(%<./)"1(,~*/)) &.|: score
rnkng=:('place';'relperf';'rel et';'rel es'),:rnkng
[rnkng=:(,.($0);'nc', 'nct',:'ncb'),.rnkng
+---+-----+-------+------+------+
| |place|relperf|rel et|rel es|
+---+-----+-------+------+------+
|nc |2 |675.04 |245.37|2.75 |
|nct|1 |241.25 | 87.69|2.75 |
|ncb|0 | 1.00 | 1.00|1.00 |
