It's A Very Small Word!

[teebee]

My solution is 56 instructions long. Is there a smaller one?

Moreover, I could write a program with 58 instructions that prints out 'Hello, Small World!' and does not grow the operand stack larger than 25.

What about adding a corresponding "King of the Hill" challenge to the "It's A Very Small Word!" and "It's a Very Small World" challenges?

Yes, there is a smaller one:

Code: Select all

$ hackvm.py word55.hvm
Hello, Small Word!
--
length of code: 55
number of cycles: 322
operand stack depth: 4
maximum operand stack depth: 20
call stack depth: 1
maximum call stack depth: 9

Yes, I was shortennig till my Hello, Small World! was 58 op long ... and it was rejected due to "l".
57 op long Hello, Small Word! was no problem than.

Grrr ... teebee ... how do you reduce the code size ... the 2,5 years between posts is a small satisfaction.

$ hackvm.py word55.hvm

length of code: 55

maximum operand stack depth: 20
call stack depth: 1
maximum call stack depth: 9

Grrr, I am on

Code: Select all

$ hackvm.py word55.hvm
Hello, Small Word!
--
length of code: 55
number of cycles: 338
operand stack depth: 6
maximum operand stack depth: 22
call stack depth: 1
maximum call stack depth: 9

only small step divided me from the correct solution decreasing just stack depth by 2.
Seems I calculate number of cycles diferent way than teebee.

Actually, I have 2 solutions with max stack length 19 and code length 55.
(But it's just an easy modification of the solution)

The hardest part was letting the VM stop.
But 55 instructions? No way! End of road...
