Time	Narration
00:01	Paralok, ngi pdiangsngewbha ia phi sha ka spoken tutorial halor ka Optimization of Linear Functions with Linear Constraints Using Scilab.
00:10	Ha kane ka jinghikai, ngin sa pule:
00:12	Kamut aiu Optimization?
00:15	Bad kumno ban pyndonkam ia ka Scilab function karmarkar, na ka bynta ka optimization.
00:20	Optimization kamut
00:22	Ban minimize lane maximize ia ka objective function ba la ai.
00:26	Ia kaba la khot ruh teng teng kum ka Cost function,
00:30	Da kaba pynpher ia ki decision variables
00:33	Ki decision variables kidei ki bynta bapher sha ki predefined constraints.
00:38	Kine ki constraints kidei ruh ha ka form jong katto katne ki functions jong ki variables.
00:44	Optimization la pyndonkam bha ha kiba bun ki engineering bad kumjuh ruh ki bym dei ki bynta ka engineering kum:
00:52	Economics
00:54	Control Theory bad
00:56	Operations & Research.
00:58	Ka Scilab function karmarkar la pyndonkam na ka bynta
01:01	Ban optimize ia ka linear objective function,
01:05	Katkum ki linear constraints
01:07	Ha ki decision variables.
01:10	Ngin sa solve ia ka nuksa kaba bud da kaba pyndonkam ia ka karmarkar function:
01:14	Minimize minus three 'x' one minus 'x' two minus three 'x' three
01:19	Na ka bynta: two 'x' one plus 'x' two plus 'x' three less than or equal to two.
01:26	'x' one plus two 'x' two plus three 'x' three less than or equal to five.
01:32	two 'x' one plus two 'x' two plus 'x' three less than or equal to six.
01:36	Ha kaba 'x' one 'x' two 'x' three baroh kidei greater than lane equal to zero
01:42	Phin iohi ba baroh ki functions , objective functions bad kumjuh ruh ki constraints, kidei linear.
01:49	Shwa ba ngin solve ia ka problem ba la ai, leit sha ka scilab console bad type:
01:54	help karmarkar
01:57	Bad nion Enter.
01:59	Phi lah ban iohi ia ka calling sequence jong ka argument.
02:03	Ki jingbatai shaphang argument, ka jingbatai bniah bad katto katne ki nuksa ha ka Help Browser.
02:12	Khang noh ia ka Help Browser .
02:14	Ngin batai kyllum ia ka input bad output arguments hangne.
02:19	Ki output arguments kidei 'x' opt, 'f' opt, exitflag, iter, 'y' opt .
02:25	'x' opt: udei u optimum solution .
02:28	'f' opt: udei u objective function value ha ka optimum solution
02:33	'exitflag' : kadei ka status jong ka execution , ka iarap ban pynithuh lada ka algorithm kadei converging ne em.
02:41	'iter' : udei u number jong ki iterations ba donkam ban poi sha 'x' opt.
02:46	'y' opt : kadei ka structure kaba don ia ka artylli ki solution.
02:49	Kane ka ai ia ki Lagrange multipliers.
02:53	Ki input arguments kidei 'Aeq' 'beq' 'c' 'x zero' 'rtolf 'gam' 'maxiter' 'outfun' 'A' 'b' 'lb' and 'ub'
03:09	'Aeq'  : udei u matrix ha ki linear equality constraints.
03:12	'beq'  : kadei ka liang kamon jong ka linear equality constraint.
03:17	'c'  : udei u Linear objective function coefficients jong u 'x'.
03:21	'x' zero : udei u Initial guess .
03:25	rtolf : udei u Relative tolerance ha u 'f' of 'x' is equals to 'c' transpose multiplied by 'x'.
03:34	'gam'  : udei u Scaling factor.
03:36	'maxiter'  : udei u maximum number jong ki iterations uba hadien jong u ia ka output la pynphai.
03:43	'outfun'  : kadei ka user-defined output function ba la bynrap lang.
03:47	'A' : udei u Matrix jong ki linear inequality constraints
03:51	'b' : kadei ka liang kamon jong ki linear inequality constraints.
03:55	'lb' : udei u lowerbound jong u 'x'.
03:58	'ub' kidei ki upper bound jong u 'x'.
04:02	Mynta, ngi lah ban solve ia ka nuksa ba la ai ha ka Scilab da kaba pyndonkam ia ka karmarkar function.
04:07	Leit sha ka scilab console bad type:
04:11	'A' is equals to open square bracket, two <space> one <space> one <semicolon> one <space> two <space> three <semicolon> two <space> two <space> one, close the square bracket
04:26	Bad nion Enter.
04:28	Ha kajuh ka rukom type: small 'b' equals to open square bracket, two <semicolon> five <semicolon> six, khang noh ia u square bracket.
04:38	Bad nion Enter.
04:41	Type: 'c' equals to open square bracket, minus three <semicolon> minus one <semicolon> minus three, close the square bracket.
04:53	Bad nion Enter.
04:55	Type: 'lb' equals to open square bracket, zero <semicolon> zero <semicolon> zero, close the square bracket.
05:05	Bad nion Enter.
05:07	Mynta clear ia ka console da kaba pyndonkam ia ka clc command.
05:12	Type: open square bracket, 'x' opt <comma> 'f' opt <comma> 'exitflag' <comma> iter, close the square bracket equals to karmarkar open parenthesis, open square bracket, close the square bracket <comma> open square bracket, close the square bracket <comma> 'c' <comma> open square bracket, close the square bracket <comma> open square bracket, close the square bracket <comma> open square bracket, close the square bracket <comma> open square bracket, close the square bracket <comma> open square bracket, close the square bracket <comma> capital 'A' <comma> 'small b' <comma> 'lb', close the round bracket.
06:09	Bad nion Enter.
06:11	Nion Enter ban bteng ia ka display.
06:14	Kane kan ai ia ka output kumba la pyni ha ka screen
06:18	Ha kaba xopt udei u optimum solution sha ka problem,
06:23	fopt udei u value jong ka objective function, ba la khein ha ka optimum solution x is equal to xopt
06:32	Bad u number jong ka iteration ba donkam ban poi sha ka optimum solution xopt udei 70
06:39	Sngewbha kynmaw ba: ka long kaba donkam ban pynshai ia ki input arguments ha kajuh ka order
06:46	Ha kaba la dep list ia ki hajrong ha kapor ba call ia ka function
06:51	Ha kane ka jinghikai, ngi la pule shaphang:
06:53	Kaei ka optimization?
06:55	Pyndonkam ia ka Scilab function karmarkar' ha ka optimization ban solve ia ki linear problems.

07:08	Peit ia ka video ba don ha ka link harum.
07:10	Ka kyllum lang ia ka Spoken Tutorial project.
07:14	Lada phim don ia ka bandwidth kaba biang, sngewbha download bad peit ia ka.

07:20	Ka pynlong ia ki workshops da kaba pyndonkam da ki spoken tutorials.
07:23	Ka ai certificates sha kito kiba pass ha ka online test.
07:27	Na ka bynta khambun ki jingtip ba bniah, sngewbha thoh sha ka contact@spoken-tutorial.org.
07:34	Spoken Tutorial Project kadei shi bynta jong ka Talk to a Teacher project.
07:37	La kyrshan ia ka da ka National Mission on Eduction lyngba ka ICT, MHRD,Sorkar India.
07:44	Kham bun ki jingtip halor kane ka mission kidon ha spoken-tutorial.org/NMEICT-Intro.
07:53	Nga i Meboreen na Shillong nga pynkut ia kane.
07:57	Khublei shibun ia ka jingsnohktilang jong phi.
