v1.6.1

v1.6.1 - 17 November 2024

• Add pointwise_max, pointwise_min arguments to take pointwise maximum or minimum of CDFs.
• Add Die.time_to_sum() method.
• Fix identification of absorbing states in the presence of extra_args in map_and_time().
• Add time_limit parameter to map().
• repeat parameter now uses 'inf' to request the absorbing distribution rather than None.

v1.6.0

v1.6.0 - 20 September 2024

• Breaking change: outcomes with zero quantities are removed when constructing Die and Deck.
  • Functions and methods relating to zero-quantities are removed: align(), align_range(), Population.has_zero_quantities(), Die.trim(), Die.set_range(), Die.set_outcomes().
  • You can use consecutive() or sorted_union() to get an appropriate superset of sets of outcomes.
• Breaking change: MultisetEvaluator.alignment() is renamed to MultisetEvaluator.extra_outcomes().
  • MultisetEvaluator.range_alignment() is renamed to MultisetEvaluator.consecutive().
  • The Alignment class is no longer public.
• Breaking change: Deck.multiply_counts() and Population.scale_quantities() are replaced/renamed to Population.multiply_quantities() etc.
• Add Deck.sequence() and Die.sequence() method.
• Add Population.pad_to_denominator() method.
• Move zero() and zero_outcome() from Die to Population.
• @ operator now sums left-to-right.
• Remove old compair evaluation.
• min_outcome() and max_outcome() free functions can now be called using a single iterable argument.
• Forward algorithm now has a persistent cache.
• Add skip optimization for single deals with keep tuples.
• Pools now only skip dice, not outcomes. This is a bit slower in some cases but provides more consistent iteration order.
• Add shared evaluator instances for some built-in evaluator for caching.
• Simplify determination of outcome order for multiset evaluations.
• Simplify implementation of generator unbinding.
• Fix extra_args expansion for map_and_time.

v1.5.0

• Providing only a drop argument to lowest() or highest() will now keep all other elements rather than just the first non-dropped element.
• depth argument to Die.reroll() is now mandatory.
• tuple outcomes are now auto-tupleized again during Die construction.
• Add Die.stochastic_round() method.
• Add Die.reroll_to_pool() method.
• Add Die.keep() method. This works as MultisetGenerator.keep() with an implicit sum.
• Add percent option to Population.probability.
• Add new again_count mode for handling Again, which limits the total number of dice.
• Improved ability to keep from both ends for certain types of multiset expressions.
• Rename func parameters to function.
• MultisetExpression.order() is now public.
• Improved sorting for Symbols; now compares counts in alphabetical order.
• Experimental sort_match, maximum_match_highest, maximum_match_lowest expressions. sort_match replaces the compair evaluations.
• Experimental all_straights_reduce_counts and argsort multiset evaluations.
• Breaking change: nearest, quantity, quantities, probability, probabilities, keep_counts no longer have separate variants for each comparison; instead, they now take a comparison argument. quantities and probabilities now accept a comparison argument but no longer accept a list of outcomes.

v1.4.0

v1.4.0

• Rename keep_counts to keep_counts_ge. Add le, lt, gt, eq, and ne variants.
• Add count_subset evaluation that counts how many times the right side is contained in the left.
• Add ImplicitConversionError as subclass of TypeError.
• Add binary multiset operators to Deck.
• Add modulo_counts / % operation on multisets.
• Rebind generators and evaluate when fully bound non-generator expressions are given to an evaluator.
• Fix Symbols intersection.
• Fix argument order in __rfloordiv__.

v1.3.0

v1.3.0

• Fix Symbols operator priority with Population, AgainExpression.
• Added experimental map_to_pool and explode_to_pool methods.
• Split compair into compare_lt etc.
• Constructing a mixture of dice now effectively uses the old lcm_joint method, which reduces the denominator more aggressively.

v1.0.0

v1.0.0

Improve some error messages.

v0.29.0

v0.29.0

• Add HTML and BBCode options for population formatting.
• Renamed apply to map and the decorator version to map_function.
• The above now uses guess_star.
• Add default of 1 die for Die.pool().

v0.27.1

If this goes well, it may become v1.0.0.

v0.25.3

* Tuple outcomes can now be compared with single outcomes.

* Add `.keep, .highest, lowest, .middle` variants of `apply_sorted`.
* Recommend `multiset_function` be used as a decorator, add `update_wrapper`.
* Add `keep_outcomes, drop_outcomes` methods to expressions.
* Add `any` evaluation to expresions.

0.25.0

0.25.0

Expanded multiset processing with multiset expressions.

• OutcomeCountGenerator, OutcomeCountEvaluator renamed to MultisetGenerator, MultisetEvaluator.
• multiset_function is an easy way to create joint evaluators.
• Pool indexing is now relative rather than absolute.
• Renamed pool.sorted_roll_counts to pool.keep and pool.keep_tuple.
• Die versions of sum_highest etc. renamed to just highest; these always return dice.
• MultisetExpression (including generators like Pool) have highest() returning an expression.
• Die operators now does mixed vector-scalar binary operations by broadcasting the scalar.
• Add middle() methods.
• Remove *generators argument from evaluator.order(), evaluator.final_outcome().
• *generators argument of evaluator.alignment replaced with the union of all generator outcomes.
• Removed suits.
• Stop using __class_getitem__, which is intended for typing only.
