Digital Slot Inspection -

  1. Slots is a Python library designed to allow the user to explore and use simple multi-armed bandit (MAB) strategies. The basic concept behind the multi-armed bandit problem is that you are faced with n choices (e.g. Slot machines, medicines, or UI/UX designs), each of which results in a 'win' with some unknown probability.
  2. The document also describes possible usage of the slots. Cold reset - document describing reset types for the platform. Firmware flashing - document describes how to flash new firmware for apu2 board on various operating systems. Also there is a description how to safely reboot the platform after a firmware update.
  3. Play 30+ FREE 3-reel and 5-reel slots: Mountain Fox, Treasures of Egypt, Flaming Crates, Prosperous Fortune, Magic Wheel, Fruit Smoothie, Party Bonus, Video Poker and more!
  4. This slot game I was playing on my phone was really simple. It had only 3 slots with different items in each. You had to push the Spin button in order to spin the slots, and you would win a small amount of coins if two or three slots were alike. Of course, 3 slots were better than 2.

What are slots?

  • For the System object: A way to map between applied parameters in a System and the underlying graph molecule(s)
  • For ParameterHandlers: A way to look at a Topology and determine
    • how many parameters should be assigned
    • whether one SMIRKS parameter should clobber another, or both parameters should coexist
  • In formal math: An customizable language (algebra?) for describing how to take a graph where each node has a unique index and:
    • enumerate desired graph substructures
    • define an equivalence operator for graph substructures

The keys in the above dictionary are our current solution to 'slots'.We've made our own dictionary subclasses like ValenceDict and ImproperDict with custom __keytransform__ methods which operate by canonically ordering the atom indices in each SMARTS match, such that they produce intentional key collisions.For example, a Bond SMARTS that matches particles (2,1) should collide with a previous match on (1,2).In this case, the desired algorithm is simple -- the particle indices are simply sorted.

This becomes slightly more complex for Angles, where naive sorting may mangle the identity of the central atom, which would mangle the calculation of the geometric angle.So the central atom in an Angle is 'priveleged', and is immune to the sorting.

Ditto for ProperTorsions and the two central positions.However, for ProperTorsions, we encounter the complexity that, IF the outer atoms are switched by the sorting, THEN the inner atoms must also be switched.


For ImproperTorsions, the second/central atom is 'priveleged', and the other three atoms are sorted.However, this sorting simply identifies the ordering for key collisions.After key collisions resolve which improper parameter should be applied, the 'trefoil' rules apply the desired improper three times, each with 1/3rd of the actual k value, on three 'canonical' orderings, which are determined by the Topology's indexing system.Specifically, of the six possible permutations of three non-central atoms, it selects the three where the first particle index in the tuple is smaller than the last.The selection of these three sortings is funcitonally important -- It makes the energy of the improper deterministic.If the three permutations were not assigned this way, the same geometry might yield different energies for different atom orderings.

LibraryCharges introduce the possibility of 'decomposability' and 'partial overlap'.Partially-overlapping LibraryCharge SMARTS might be used when many molecules have a common or repeating substructure, but their charges differ for a small functional group.In effect, a LibraryCharge parameter with N tagged atoms is applied as if it had been decomposed into N separate LibraryCharge parameters with one tagged atom each.

You'll start with $50. You'll be asked if you want to play.

For example you can answer with YEs, yEs, Y, nO, N.
To win you must get one of the following combinations:

Instead of;
if(answer 'yes' or answer 'y'):

if answer.lower() in ['yes',y']

I run it on python 2 ,it's need to modify the 43 line (input -> raw_input)
