class VirtualDate::Scheduler

• VirtualDate::Scheduler
• Reference
• Object

Overview

A simple, deterministic scheduler for VirtualDate vdates.

This scheduler:

• Generates candidate candidates from vdate.due VirtualTimes
• Resolves omit-driven shifts via VirtualDate#resolve
• Enforces conflict resolution using duration, flags, parallel
• Reschedules forward on conflicts when possible

Notes:

• This is an “advanced baseline” scheduler; it is intentionally conservative and predictable.
• If you need global optimality (e.g. minimizing total displacement), you would add a second pass or switch to a constraint solver.

Defined in:

virtualdate.cr

Constructors

• .new(vdates : Array(VirtualDate) = [] of VirtualDate)

Instance Method Summary

• #build(from : Time, to : Time) : Array(Scheduled)

  Produces scheduled vdates in [from, to).

• #on_in_schedule?(scheduled_vdates : Array(Scheduled), vdate : VirtualDate, time : Time) : Bool

  True if vdate is considered “on” at time in the produced schedule.

• #schedule_candidate(candidate : Candidate, scheduled_vdates : Array(Scheduled), *, horizon : Time) : Scheduled | Nil

  Schedules a vdate, resolving conflicts by shifting forward (using vdate.shift when Time::Span), respecting vdate.fixed and max_shift/max_shifts.

• #vdates : Array(VirtualDate)
• #vdates=(vdates : Array(VirtualDate))
