We also use it as a priority queue (sometimes called a heap ) in step D6, when we need to know the pair with maximum volatilit.y Both of those operations, as well as the insertion of new pairs …

uint *heap; /* priority queue for sorting variables by their activity */ int hn; /* number of items currently in the heap */ uint *trail; /* literals currently assumed, or forced by those assumptions …

All of these lists --- the triggers, the fixits, and the queue --- are singly linked, in a array called |pool|, whose elements have two fields called |info| and |link| in familiar fashion. The trigger …

into an octabyte. The memory is treated as a cyclic queue, wrapping around from |mem[memsize-1]| to |mem[0]|. Link |l| therefore points to the block of |b| octas that begin at location …

uint look_cs,dlook_cs; /* saved values of |cs| */ int fptr,eptr,lfptr; /* queue pointers for breadth-first search */ @ Here's a simple routine for use in debugging. It prints out all literals that are true …
