@name Encoding/decoding problem index

General schema for encoding/decoding a problem index. Note that the index depends on the number of instances a suite is defined with (it should be called a suite-instance-depending index…). Also, while functions, instances and dimensions start from 1, function_idx, instance_idx and dimension_idx as well as suite_dep_index start from 0!

Showing an example with 2 dimensions (2, 3), 5 instances (6, 7, 8, 9, 10) and 2 functions (1, 2):

\verbatim index | instance | function | dimension ——+–––––+–––––+———– 0 | 6 | 1 | 2 1 | 7 | 1 | 2 2 | 8 | 1 | 2 3 | 9 | 1 | 2 4 | 10 | 1 | 2 5 | 6 | 2 | 2 6 | 7 | 2 | 2 7 | 8 | 2 | 2 8 | 9 | 2 | 2 9 | 10 | 2 | 2 10 | 6 | 1 | 3 11 | 7 | 1 | 3 12 | 8 | 1 | 3 13 | 9 | 1 | 3 14 | 10 | 1 | 3 15 | 6 | 2 | 2 16 | 7 | 2 | 3 17 | 8 | 2 | 3 18 | 9 | 2 | 3 19 | 10 | 2 | 3
