GAL := 3*sqrt(6)/((2*x^2+3)*sqrt(4*x^2+6));

simplify(GAL) and combine(GAL,power)

have same result.

How to make them return

3*sqrt(3)/(2*x^2+3)^(3/2) ?

Besides of other things i should also analyze what happens with function at y=0. For now IntermediateCalc incapsulates limit but it too slow. What can you suggest better? Tried series but there is the problem that function is only defined at right of 0, there is no expansion in this case. See attach for deatails. main.mw

test.zip

1) Compile under vc express 2010 debug config. Don't forget point out your location of maplec.lib in configuration properties/Linker/General/Additional library directories. Assure that configuration is at least Debug or all.

2) Run sheet test_bombard.mw from Debug directory.

Have permanent crash on BombardByRandoms call. If i would transmit creating of rtable from 'InitInternal'...

main.mw

Please, start attach from beginning till that place where 

Have a piece of code:with(Optimization):

with(ExternalCalling):
MyTargetMultArgsFunctionExt := define_external('MyTargetMultArgsFunctionExt', 'MAPLE', x::(float[8]), y::(float[8]), 'LIB' = "maple_library.dll");
G := proc (x, y) options operator, arrow; MyTargetMultArgsFunctionExt(x, y) end proc;
dMyTargetMultArgsFunctionExtr0 := proc (x, y) options operator, arrow; x^2 end proc;
Minimize(G)

After which i obtain warning:
