+
+    // If this instance has several [block]s, it will shuffle them in randomized order and measure the time.
+    // [nSingleMeasureLoop] represents how many times a block is executed in one measurement.

+    nSingleMeasureLoop = 5
+
+    // In the early executions, the execution of the [block] takes more time,
+    // so we first perform some executions which are not counted in the measurements.
