Acceptance ratios too high! #17

Closed jh041 closed 4 years ago

jh041 commented 4 years ago

Hi, Maps is accepting the MCMC proposals way to often. 

Acceptance proportions:
    (811682/907853) = 89.41% for type "qTileRate"
    (834328/882231) = 94.57% for type "qTileMove"
    (808129/884221) = 91.39% for type "qBirthDeath"
    (990770/1250257) = 79.25% for type "qMeanRate"
    (814962/905844) = 89.97% for type "mTileRate"
    (516004/882092) = 58.50% for type "mTileMove"
    (834444/882335) = 94.57% for type "mBirthDeath"
    (1216077/1250433) = 97.25% for type "mMeanRate"
    (904632/937567) = 96.49% for type "omegaM"
    (819137/936663) = 87.45% for type "omegaQ"
    (5543/140097) = 3.96% for type "eqBar"
    (4833/140407) = 3.44% for type "emBar"

Any ideas on how to get the acceptance ratios into a more optimal range? What parameters should I modify and how?

Also, my .ini input file was copied and pasted from the example, and doesn't have all the parameters in the mapsrun.txt output. Can I simply add these parameters into the .ini file?

Thanks for your help,

John
