\"\"Make a vague comparison between two items a<\/em> and b<\/em> sharing a common ordered series.<\/p>\n

This instruction is one of the few that cannot use Booleans; it requires a traditional resolution: returning to the statement several times. This is why this type of comparison is called vague.<\/em> The common ordered series does not need to be regular.<\/p>\n

Ordered series: A series containing values \u200b\u200bthat are all increasing or all decreasing.
\nRegular ordered series: An increasing or decreasing series whose values \u200b\u200bare separated by the same interval.<\/h6>\n

\"\"<\/p>\n

 <\/p>\n

Generally, with this instruction, there are few boxes to be cleared at<\/em> the beginning of the puzzle: the teenager in the blue tank cannot train for 20 minutes, the 13-year-old cannot train for 1 hour and does not use the blue tank. You will therefore have to return to this instruction several times, as the puzzle progresses.<\/p>\n

Designer<\/h1>\n

\"\"<\/p>\n

Choose two items a and b and an order relation D, such that D(a) < D(b).<\/p>\n

\"\"<\/p>\n

If the instruction operates in isolated mode, the designer randomly chooses, for each item, a row (line or column) whose boxes are all empty (no true<\/em> , no false<\/em> , no booleans).<\/p>\n

\"\"<\/p>\n

Maximum number of instruction executions.<\/p>\n

a, b items belonging to two different series or to the same series.

We can obviously transform a < b into b > a!<\/p>\n
