Revision as of 16:01, 29 April 2019

Update

valid as for Aug 5, 2018

Learning

  • Algorithm SM-18 with a new approach to determining item difficulty
  • new universal algorithm metric
  • simplified editing of repetition histories (e.g. Aug 15, 1995 or Int=6 are allowed instead of full repetition data)
  • recalibrating SuperMemo Algorithm to rely on E(SInc[]) rather than SInc[]
  • maximum interval increased to 120 years (previously 10,000 days, i.e. 37 years)
  • repetition history can be used to override learning parameters
  • Undo Repetition (items are made pending when the last record is deleted)
  • grade undo is possible by editing the last repetition history record (or Undo Repetition)

Interface

  • 40 predefined themes (skins)
  • each collection can use its own theme (skin)
  • all toolbars available as tabs at the bottom of the element window
  • vivid emojis used for grades (as opposed to standard grade names known from previous SuperMemos)

    Emoji-based grade panel in SuperMemo 18

    Figure: In SuperMemo 18, grades are illustrated with vivid emojis by default. If you prefer the old text-based grades (i.e. Great, Pass, Bad, etc.), uncheck Grade icons in Toolkit : Options : SuperMemo.

  • parenting browser with element window make it possible to use all its shortcuts

Performance

  • SuperMemo 18 has been recompiled with Delphi 10.2 Tokyo
  • minimizing add on units to capitalize on native Delphi support
  • resetting statistics at Memorized=0 does not reset the collection, only deletes files

Bugs fixed

  • https:// image import could fail for not http:// equivalent
  • occasionally, RTF files would fail to upgrade to HTML (old format retained)
  • Alarm : Start could instantly raise the alarm for time>0

Warnings

  • No more floating toolbars
  • No more toolbar dock
  • No more translation import and export via text
  • Window:Select:Next window removed
  • No more stray repetition export from repetition history
  • Additional repetition history warnings Wrong repetition, grade and lapses match can only be fixed manually (e.g. Fix and Edit)

Other

  • simplified code with a great deal of refactoring
  • 440 improvements and bug fixes
