1047 :
1048 : This is a tricky task, however. All our notions of priority and
1049 : better/worse are based on static information about the transaction,
1050 : and there's not an easy way to take into account global
1051 : information, for example, how many other transactions contend with

1053 : need pop-min, insert, and delete) with one element for each element
1054 : in the pool, with a "delete me" score that's related but not
1055 : identical to the normal score. This would allow building in some
1056 : global information. The downside is that the global information
1057 : that gets integrated is static. E.g. if you bias a transaction's
1058 : "delete me" score to make it more likely to be deleted because
1059 : there are many conflicting transactions in the pool, the score
1060 : stays biased, even if the global conditions change (unless you come
1061 : up with some complicated re-scoring scheme). This can work, since
1062 : when the pool is full, the global bias factors are unlikely to
1063 : change significantly at the relevant timescales.
1064 :
1065 : However, rather than this, we implement a simpler probabilistic
1066 : scheme. We'll sample M transactions, find the worst transaction in
1067 : each of the M treaps, compute a "delete me" score for those <= M
1068 : transactions, and delete the worst. If one penalty treap is
1069 : starting to get big, then it becomes very likely that the random
1070 : sample will find it and choose to delete a transaction from it.
1071 :
1072 : The exact formula for the "delete me" score should be the matter of
1073 : some more intense quantitative research. For now, we'll just use
1074 : this:
1075 :
1076 : Treap with N transactions Scale Factor
1077 : Pending 1.0 unless inserting a vote and votes < 25%
1078 : Pending votes 1.0 until 75% of depth, then 0
1079 : Penalty treap 1.0 at <= 100 transactions, then sqrt(100/N)
1080 : Pending bundles inf (since the rewards value is fudged)

1523 : within the bundle is determined at bundle creation time, and the
1524 : order among the bundles is FIFO. However, it's going to be a pain
1525 : to use a different sorting function for this treap, since it's
1526 : fixed as part of the treap creation for performance. Don't fear
1527 : though; we can pull a cool math trick out of the bag to shoehorn
1528 : the order we'd like into the sort function we need, and to get even
1529 : more.
1530 :
1531 : Recall that the sort function is r_i/c_i, smallest to largest,
1532 : where r_i is the rewards and c_i is the cost units. r_i and c_i
1533 : are both uints, and the comparison is done by cross-multiplication
1534 : as ulongs. We actually use the c_i value for testing if
1535 : transactions fit, etc. so let's assume that's fixed, and we know
1536 : it's in the range [1020, 1,556,782].
1537 :
1538 : This means, if c_0, c_1, ... c_4 are the CU costs of the
1539 : transactions in the first bundle, we require r_0/c_0 > r_1/c_1 >
1540 : ... > r_4/c_4. Then, if c_5, ... c_9 are the CU costs of the
1541 : transactions in the second bundle, we also require that r_4/c_4 >
1542 : r_5/c_5. For convenience, we'll impose a slightly stronger
1543 : constraint: we want the kth bundle to obey L*(N-k) <= r_i/c_i <
1544 : L*(N+1-k), for fixed constants L and N, real and integer,
1545 : respectively, that we'll determine. For example, this means r_4/c_4
1546 : >= L*N > r_5/c_5. This enables us to group the transactions in the
1547 : same bundle more easily.
1548 :
1549 : For convenience in the math below, we'll set j=N-k and relabel the
1550 : transactions from the jth bundle c_0, ... c_4.
1551 : From above, we know that Lj <= r_4/c_4. We'd like to make it as
1552 : close as possible given that r_4 is an integers. Thus, put
1553 : r_4 = ceil( c_4 * Lj ). r_4 is clearly an integer, and it satisfies
1554 : the required inequality because:
1555 : r_4/c_4 = ceil( c_4 * Lj)/c_4 >= c_4*Lj / c_4 >= Lj.
1556 :
1557 : Following in the same spirit, put r_3 = ceil( c_3 * (r_4+1)/c_4 ).
1558 : Again, r_3 is clearly an integer, and
1559 : r_3/c_3 = ceil(c_3*(r_4+1)/c_4)/c_3
1560 : >= (c_3*(r_4+1))/(c_3 * c_4)
1561 : >= r_4/c_4 + 1/c_4
1562 : > r_4/c_4.
1563 : Following the pattern, we put
1564 : r_2 = ceil( c_2 * (r_3+1)/c_3 )
1565 : r_1 = ceil( c_1 * (r_2+1)/c_2 )
1566 : r_0 = ceil( c_0 * (r_1+1)/c_1 )
1567 : which work for the same reason that as r_3.
1568 :
1569 : We now need for r_0 to satisfy the final inequality with L, and
1570 : we'll use this to guide our choice of L. Theoretically, r_0 can be
1571 : expressed in terms of L, j, and c_0, ... c_4, but that's a truly
1572 : inscrutible expression. Instead, we need some bounds so we can get
1573 : rid of all the ceil using the property that x <= ceil(x) < x+1.
1574 : c_4 * Lj <= r_4 < c_4 * Lj + 1
1575 : The lower bound on r_3 is easy:
1576 : r_3 >= c_3 * (c_4 * Lj + 1)/c_4 = c_3 * Lj + c_3/c_4
1577 : For the upper bound,
1578 : r_3 < 1 + c_3*(r_4+1)/c_4 < 1 + c_3*(c_4*Lj+1 + 1)/c_4
1579 : = 1 + c_3 * Lj + 2*c_3/c_4
1580 : Continuing similarly gives
1581 : c_2*Lj + c_2/c_3 + c_2/c_4 <= r_2
1582 : c_1*Lj + c_1/c_2 + c_1/c_c + c_1/c_4 <= r_1
1583 : c_0*Lj + c_0/c_1 + c_0/c_2 + c_0/c_3 + c_0/c_4 <= r_0
1584 : and
1585 : r_2 < 1 + c_2*Lj + 2c_2/c_3 + 2c_2/c_4
1586 : r_1 < 1 + c_1*Lj + 2c_1/c_2 + 2c_1/c_3 + 2c_1/c_4
1587 : r_0 < 1 + c_0*Lj + 2c_0/c_1 + 2c_0/c_2 + 2c_0/c_3 + 2c_0/c_4.
1588 :
1589 : Setting L(j+1)>=(1 + c_0*Lj+2c_0/c_1+2c_0/c_2+2c_0/c_3+2c_0/c_4)/c_0
1590 : is then sufficient to ensure the whole sequence of 5 fits between Lj
1591 : and L(j+1). Simplifying gives
1592 : L<= 1/c_0 + 2/c_1 + 2/c_2 + 2/c_3 + 2/c_4
1593 : but L must be a constant and not depend on individual values of c_i,
1594 : so, given that c_i >= 1020, we set L = 9/1020.
1595 :
1596 : Now all that remains is to determine N. It's a bit unfortunate
1597 : that we require N, since it limits our capacity, but it's necessary
1598 : in any system that tries to compute priorities to enforce a FIFO
1599 : order. If we've inserted more than N bundles without ever having
1600 : the bundle treap go empty, we'll briefly break the FIFO ordering as
1601 : we underflow.
1602 :
1603 : Thus, we'd like to make N as big as possible, avoiding overflow.
1604 : r_0, ..., r_4 are all uints, and taking the bounds from above,
1605 : given that for any i, i' c_i/c_{i'} < 1527, we have
1606 : r_i < 1 + 1556782 * Lj + 8*1527.
1607 : To avoid overflow, we assert the right-hand side is < 2^32, which
1608 : implies N <= 312671.
1609 :
1610 : We want to use a fixed point representation for L so that the
1611 : entire computation can be done with integer arithmetic. We can do
1612 : the arithmetic as ulongs, which means defining L' >= L * 2^s, and
1613 : we compute ceil( c_4*Lj ) as floor( (c_4 * L' * j + 2^s - 1)/2^s ),
1614 : so c_4 * L' * j + 2^s should fit in a ulong. With j<=N, this gives
1615 : s<=32, so we set s=32, which means L' = 37896771 >= 9/1020 * 2^32.
1616 : Note that 1 + 1556782 * L' * N + 8*1527 + 2^32 is approximately
1617 : 2^63.999993.
1618 :
