DESCRIPTION:This seminar is a candid review of the Pandora software projec
 t\, which originated 20 years ago in the context of the International Line
 ar Collider (ILC). Vital lessons were learned about what it really takes t
 o deliver a Particle Flow Algorithm (PFA)\, via the implementation of the 
 highly-successful package PandoraPFA. These lessons then fed into a two-ye
 ar programme of software engineering\, in which the Pandora Software Devel
 opment Kit (SDK) was created\, and PandoraPFA completely reimplemented. Th
 e Pandora SDK supports a multi-algorithm approach to pattern recognition\,
  in which large numbers of algorithms gradually build up a picture of comp
 lex events. The new PandoraPFA successfully delivered a programme of physi
 cs-sensitivity and detector-optimisation studies for both the ILC and Comp
 act Linear Collider (CLIC). The modular design of the Pandora SDK then ope
 ned up an all-new opportunity\, in the realm of neutrino physics: the reco
 nstruction of events in Liquid-Argon Time-Projection Chamber (LArTPC) dete
 ctors. LArTPC detectors can provide “photograph-quality” images of the
  charged particles emerging from neutrino interactions\, but the images ca
 n be extremely complex and difficult to interpret. The Pandora LArTPC reco
 nstruction has seen extensive use at the MicroBooNE experiment\, and is no
 w used by SBND and ICARUS too. Today\, it is being developed for use at th
 e Deep Underground Neutrino Experiment (DUNE)\, in order to unlock the phy
 sics potential of DUNE’s imaging detectors. This seminar will review som
 e of the key Pandora milestones\, as well as the pattern-recognition algor
 ithms deployed for use at e+e- linear colliders and for LArTPC detectors. 
 Some current development highlights at DUNE will be introduced\, alongside
  a few reflections about this now long-running project.
