Editing Derandomization

The process of '''derandomization''' is a method used on [[random-element]] <!---No hyphen = the walkers, blobs and random force floors. This is the level theme.---> levels, where the [[Melinda]] time would be extremely difficult to achieve, to determine the Melinda time. In a separate, unofficial level, the [[random element]]s are either replaced with nonrandom tiles or are simply removed altogether. The resulting score, assuming that this can still be done with the random elements, is the Melinda time.

In extreme cases such as [[Monster Lab]] or [[Lead Us Not into Temptation]], a temporary [[AVI]] solution is used as the official solution until it can be scored with the real level; as derandomization was not developed until after [[Chip's Challenge Level Pack 2|CCLP2]], such measures have only been utilized for the rare [[CCLP3]] levels with random elements.

== Replacing derandomization ==

There are two types of derandomization, depending on the nature of the random elements. For random [[force floor]]s, they are typically replaced with other [[sliding tile]]s which still allow the same [[boosting]] overrides. Often [[ice]] is put ahead of each force floor, but sometimes force floors against each other are also used. One historical example is [[Mads' Rush II]]:

To reach the [[bold time]] of 26, Chip would have to be moved R off [2, 3], R or D off [4, 3], and depending on that, either D off [5, 4] or R/D off [4, 5]/[5, 4] (the latter depending on which override off [4, 4] Chip takes), then after hitting the [[green button]], U off [5, 4] and R off [6, 3]. As the chances of this work out to 1 in 512 ([1/4]^4 * 1/2), this was not scored for a long time. When derandomized, the section will look somewhat like this:

== Destroy derandomization ==

When [[walker]]s or [[blob]]s interfere instead, it can often be easier to derandomize. Frequently, the solution would be to simply remove the offending monsters, as one might do for [[Oorto Geld II]]:

Here, the walkers control nothing in the level unless they run into the center (very unlikely), and destroying them would make determining the Melinda time much easier. It was eventually found to be 671, but derandomization might have made it simpler to write the route.
