In science:

Each step of the list machine corresponds to the sequence of Turing machine steps that are performed by T while none of its external memory tape heads changes its direction or leaves its current tape block.
Randomized Computations on Large Data Sets: Tight Lower Bounds
As long as no head of the external memory tapes of T changes its direction or crosses the boundaries of its current block, M does not do anything.
Randomized Computations on Large Data Sets: Tight Lower Bounds
A new cell is inserted into the lists behind the head, this cell represents the newly created tape block that is behind the head.
Randomized Computations on Large Data Sets: Tight Lower Bounds
The newly created block starting with the current head position is represented by the (old) cell on which the head still stands.

This means that “random bits” 0 (head) and 1 (tail) can thus be generated and grouped into blocks that then can be used to produce, for example, integers of a given size (for example, 32 coin tosses can be used to produce a 32-bit integer).

Bounded Counter Languages
The counters will store distances between head positions and boundaries of blocks of the input, where distances to left or right boundaries may occur in the course of the simulation.
Bounded Counter Languages
Each interval starts with a configuration in which at least one head is next to a boundary (i.e., on one of the two positions left or right of the boundary between blocks), one of these heads being represented by C ’s pointer.
