Hi Jim,<br>
<br>
Thanks for the corrections. Here are my updated results<br>
with some trial solutions for outputs 9 and 10.<br>
I differ in output 10.<br>
<br>
$ echo 33009 9002 11 | ../bin/cnc<br>
Input:<br>
RegP: 33009 bits: 1000000011110001<br>
RegM: 9002 bits: 0010001100101010<br>
RegS: 11 bits: 00001011<br>
Output #1: 241 (position) bits: 11110001<br>
Output #2: 35 (velocity) bits: 00100011<br>
Output #3: 2 (accel.) bits: 00000010<br>
Output #4: 10 (time) bits: 00001010<br>
<br>
Error status:<br>
Position error.<br>
Velocity ok.<br>
Acceleration error.<br>
Time error.<br>
<br>
Error corrected:<br>
Output #5: 240 (position) bits: 11110000<br>
Output #6: 35 (velocity) bits: 00100011<br>
Output #7: 10 (accel.) bits: 00001010<br>
Output #8: 9 (time) bits: 00001001<br>
<br>
Error status:<br>
Position ok.<br>
Velocity ok.<br>
Acceleration ok.<br>
Time ok.<br>
<br>
Output #9:<br>
Travel time t: 6.93 (s)<br>
final velocity v: 69.28 (cm/sec)<br>
<br>
Output #10:<br>
Testung t1 solution 1: 12.83 (s)<br>
Invalid t2 with t1 solution 1: -16.66<br>
trying t1 solution 2: 1.17 (s)<br>
Valid t2 with t1 solution 2: 6.66 (s)<br>
<br>
Solution t1: 1.17 (s)<br>
Solution t2: 6.66 (s)<br>
<br>
Output #11:<br>
Solutions involving a negative amount for t2 are not<br>
physically possible without time travel.<br>
