================================================================================================
This is Rakudo Perl 6 running in valgrind, a tool for debugging and profiling programs.
Running a program in valgrind usually takes *a lot* more time than running it directly,
so please be patient.
Valgrind options can be added with MVM_VALGRIND_OPTS environment variable.

This Rakudo version is 2018.12.266.g.3.d.581.c.8.d.2 built on MoarVM version 2018.12.36.g.34.fac.5.f.4.e,
running on debian (4.9.0) / linux (4.19.0.1.amd.64)

ok 1 - Given a setting of C_SVC/LINEAR, Algorithm::LibSVM.check-parameter should return True
ok 2 - Given a setting of C_SVC/LINEAR, When Algorithm::LibSVM::Model.predict<label> predicts a label of a instance (where the instance is at the center of the cluster labeled as 1 in the training set), it should return 1.0e0
ok 3 - Given a setting of C_SVC/LINEAR/:probability, Algorithm::LibSVM.check-parameter should return True
ok 4 - Given a setting of C_SVC/LINEAR/:probability, When Algorithm::LibSVM::Model.predict<label> predicts a label of a instance (where the instance is at the center of the cluster labeled as 1 in the training set), it should return 1.0e0
ok 5 - Given a setting of C_SVC/LINEAR/:probability, When Algorithm::LibSVM::Model.predict<prob-estimates> predicts a probability that given instance (where the instance is at the center of the cluster labeled as 1 in the training set) is labeled as 1, it should return a value larger than 0.25e0
