The type parameter s_ serves to keep the internal states of different cell networks separate from each other (see  for details). propellerVThe result of a propagation which allows to rollback changes and inspect its success. propeller\An action that reverts all cell changes of a propagation (both direct and transitive ones).  propellerT if the propagation was successful (i.e., it did not lead to a cell change that is  ), otherwise .INote that unsuccessful propagations are not automatically reverted. Use  to do this.  propellerŽConstructs a new cell with a given initial value and a function which defines how to react if a new value is about to be written to the cell.  propeller#Reads the value of a specific cell.  propellerxWrites a new value to a specific cell and starts to propagate potential changes through the network of connected cells.  propellereConnects a source cell to a target cell in order to propagate changes from the source to the target.dNote that newly connected cells do not start to propagate changes immediately after wiring up. Use  or  to do this. propeller‡Connects and synchronizes two cells, i.e. new values are propagated from the source to the target cell, and vice versa. Short form of     .dNote that newly connected cells do not start to propagate changes immediately after wiring up. Use  or  to do this. propellerDConnects and synchronizes two cells using two translation functions f and gK, i.e. new values are propagated from the source to the target cell using f, and vice versa using g.dNote that newly connected cells do not start to propagate changes immediately after wiring up. Use  or  to do this. propeller•Propagates the value of a specific cell to its connected cells in a transitive manner. The propagation ends if no more cell changes occur or if an " cell value change is encountered. propeller—Propagates the values of specific cells to their connected cells in a transitive manner. The propagation ends if no more cell changes occur or if an " cell value change is encountered. propellerIf the content of a Cell s a' is an accumulation of multiple values [b], and every value b itself can be used as content a. for the cell, then we can write every value bY one after another to the cell and check if the network converges to a successful state.—As a result, we can enumerate all possible combinations of valid values for a given set of cells. This is often used in constraint solving algorithms.  propellerThe initial value of the cell. propeller}A function that describes how to join an existing cell value with a new one that the cell has received via propagation. propellerThe newly constructed cell.  propellerThe source cell. propellerThe target cell. propellerxA function that describes how the value for the target cell is constructed, based on the value of the source cell. propeller2Note that no propagation takes place (i.e., no  is returned). propellerAA function which extracts testable values from a cell content. propellercA function which translates a testable value into a value which can be written back to the cell. propeller5The set of cells for which the values are enumerated. propeller2Returns all valid assignments for the given cells.
