List scheduling
Wikimedia list article

List scheduling is a greedy algorithm for Identical-machines scheduling. The input to this algorithm is a list of jobs that should be executed on a set of m machines. The list is ordered in a fixed order, which can be determined e.g. by the priority of executing the jobs, or by their order of arrival. The algorithm repeatedly executes the following steps until a valid schedule is obtained:
Take the first job in the list (the one with the highest priority).
Find a machine that is available for executing this job.
If a machine is found, schedule this job on that machine.
Otherwise (no suitable machine is available), select the next job in the list.
Example
Suppose there are five jobs with processing-times {4,5,6,7,8}, and m=2 processors. Then, the resulting schedule is {4,6,8}, {5,7}, and the makespan is max(18,12)=18; if m=3, then the resulting schedule is {4,7}, {5,8}, {6}, and the makespan is max(11,13,6)=13.
“List scheduling” enters the record as wikimedia list article. Crown Archives preserves that source wording while asking what List, scheduling and Wikimedia can confirm, complicate or overturn.
Why this record matters
“List scheduling” is worth following because a concise public description often conceals a longer documentary argument. Here, List, scheduling and Wikimedia provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 21, 2025. The linked authority identifier is Q6646016. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
